    5-0 out of 5 stars Very good for Statistics and Finance too...
    I saw many reviewers for advanced math and engineering. I just want to add that it is also very good for stat and finance. It can be calculated with almost (I'm saying this because I haven't tried every single one yet ;-) every calculation with this TI-89. The plus side is that it has bigger screen and we can change any value anytime without starting over... especially good for multiple problem solving.

    At first, I intendeded to purchase TI-BAII+ required by the professor but decided to trade this TI-89 Titanium with my old original TI-89. Both has flash applications for Statistics with List Editor and Finance as well as Data/Metrix Editor. For finance, you can get PV, FV, i, PMT, NPV, IRR, etc.

    You can also download guide books from TI's website. This is a life saver for most business classes.... I used TI-89 from advanced algebra, pre- and calculus, fin & managerial accounting, economics, 2 statistics, and financial management... 10 courses altogether ;-) And this IT-89 cost about the same price of a business text book! Of course, you'll need to know the concepts and how to use this calculator first.

    If you're wondering which one to choose between original TI89 and this new Titanium, I recommend original if you've vision problem. Original TI89 has deep purple and dark blue colors for "2nd" and "diamond" keys. This new one has very pale blue and light green keys, hard to look at if you need combination keys. SO do for the fonts and "alpha" key. As the manufacturer mentioned, this one has more memory and can be used USB cable.

    Just a tip for the two reviewers below and others about fraction and decimal switching (.25 - 1/4 switching) :
    Reviewer:MaxiMinerand Reviewer:cool dude (Stockholm)

    Just use a "period" between the calculation (if you have all whole numbers) and you'll see decimals in the result without changing the "mode" you preferred. If you have any decimals between the calculations, you'll automatically see decimals. It works for every graphing calculator. I got that tip from a Math Lab Asst. in my algebra lab.

    5-0 out of 5 stars Printed manual IS available
    Well, it's just a "short" 606 page version for the TI-89/TI-92, but it still beats dealing with 900+ pages from Titanium CD or on-line manual.
    Go to epsstore ti com Manuals/Guidebooks under TI-89 and get it for the measly 20+ (seems French and Spanish reading public gets 50% break).
    Functionally TI-89 and TI-92 are nearly identical (minus keyboard on TI-89), so you can find very nice books on TI-92, like those from Gilmar publishing, that you can apply to your Titanium.
    I had the same gripes as "cool dude" (see review below) about .25 - 1/4 switching until I started working in the exact mode, pressing [diamond][ENTER] (instead of just [ENTER]), when decimals are needed.
    Still, if I need to work with fractions and other simple things, I pull out my trusty Sharp EL-506WBBK. To switch from .25 to 1/4 and back you just toggle with the [a b/c] key.
    To get a proper function on TI-89 you have to envoke F2,7,2ND,(-),),ENTER. On Sharp: 2ndF, [a b/c].
    But then again, Titanium is crafted for much finer things. And how it does them is beyond praise.

    4-0 out of 5 stars Great Calculator - small print
    This calculator seems to do everything and do it well. My only complaint is that the alternate key functions are somewhat hard to read and the screen can be somewhat hard to read. As you can guess I use glasses. I wish TI would make a screen where the fonts size can be adjusted and perhaps even a backlit screen, otherwise a great product.

    4-0 out of 5 stars Tig Class
    This Calculator is perfect for advanced math classes. It does more than I could ever believe. The Calculator is simple to use and has a nice screen format. The main problem is that it has so much processes that you actually have to dig got the x radical sign. It can even graph in 3-d. The only thing better is one that has a colored screen.

    4-0 out of 5 stars Just a few things....
    Perhaps Im little more whiny than you jankees, because I live in Sweden and had to pay almost the double price, since Im not allowedorder it from Amazon. Some complains:

    The numbers on the screens are very small, compared to ti-83 for example. I wish their size could have been adjustable.

    There are no simple method to get a number fractioned, like make 0.25 into 1/4. You have to go to the mode menue and switch to "exact". Its irritating, on ti-83 you just chose "frac". Maybe Im missing something so if its possible on this I want to know! :P

    It just got natural and 10 logarithms. In matlab you can have log2 for example.

    Otherwise, this is a really good and flashy calculator that makes all the ordinary ti-83/86 owners go like: " what is that?!". D-) ... Read more

    5-0 out of 5 stars Very good product
    This calculator is probobly the best one that i have owned. You can create graphs with it, you can do equations, you can even do complex algebra/trigonometry/calculus on this calculator. Also, for the kids, there are games that you can download quite simply of the internet for you to play in case by any chance you get bored during math class. (Don't get any bright ideas!) I know this product is very expensive, but it is well worth it once you realize how good this product actually is. Do yourself a favor, and buy this product!

    5-0 out of 5 stars great calculator
    I found this to be a useful calculator in high school.It definitely helped me see a lot of functions and perform experiments.

    5-0 out of 5 stars The gold standard for calculators
    I purchased my TI-83 Plus in 1999 and still have it today. I have never had any problems with it and can only remember changing the batteries 3 or 4 times. I've even dropped it from my 2nd story balcony by accident (more like a friend knocked it off a table on the balcony) and it didn't break. When I turned it on after it fell, my calculations were still on the screen!

    It is easy to use and fast enough for all high school and college mathematics.

    I'd recommend it to anyone who needs a workhorse of a calculator.

    5-0 out of 5 stars Amazing
    This is a fantastic calculator that I use in my algebra class and others.You can take notes on this calculator with the Ti keybord acsseorie the acsseorie comes with a program for the calculator so you can take notes on it and save them for tests. You can also store things like study cards,games,and all those other important things you need. I highly recommend this calculator to anyone with any class.GO GET THIS CALCULATOR!=)

    5-0 out of 5 stars Too simple?I think not!
    I looked at other more "fully featured" calculators for my daughter and decided against them.It is so easy to buy more than you need in calculators and end up with something too complex/confusing for purpose.Avoid the "my calculator has got more buttons thatn your calculator" syndrome.Better to buy a more complex one in three years for college, if needed - when they will be cheaper and have even more feaures. ...

    US | Canada | United Kingdom | Germany | France | Japan Review

    If you bought yourself a financial calculator during the 1980s, chances are it was this bad boy. Nothing has changed since its introduction--it still uses Reverse Polish Notation (RPN), is easy and versatile in programming, and has a thin, sturdy casing. Certainly, there's been newer, fancier calculators introduced since, but there's something to be said for the quality of classics.

    The HP 12C's functions include all the basics--such as calculating APR, NPV, and IRR--and statistics are a snap. For students new to financial calculators, this is an excellent place to start. For the most part, the manual reads like a minitextbook, walking you through sample problems and situations followed by graphs and tables demonstrating the technique--and you can even check your results. The section on creating programs does seem to be written for the technically ignorant, addressing in detail how you could possibly benefit from using programs, but it'll still help you get the job done.

    In general, it's a bit slower than newer models, just like last year's computer isn't as speedy as today's new release. On the plus side, it's just 3 by 5 inches and slips easily into a pocket. The bottom is printed with a few little cheat notes for common functions, which is nice for quick reference. The HP 12C's one-year warranty and available tech-support line offer reassurance this little workhorse will continue to be an industry standard for years to come. --Jill Lightner

    5-0 out of 5 stars Venerable, Compact, Elegant
    I first began using this 'calc' in 1986. A commercial realtor friend told me this was what "everyone" (everyone to be taken seriously) used. I carried it on vacation, to church, to the supermarket, and everywhere, determined to learn in any spare moment its secrets and work its magic. The 12C's flat profile and compact size slips easily into a sportcoat pocket and you can rotate it continually in one hand just for fun! The User's Manual was not especially user friendly, but it was (is still?) a key to the treasure. It also can be easily slipped into a pocket, but I found the glossy pages annoyingly difficult to pencil-in notes.HP also makes the cheaper 10B II calc that the College for Financial Planning (CFP) recommends for their coursework. I often use it at work, and when teaching at a local college I am not inclined to require students buy the more expensive HP 12C. The more expensive HP 17B II leaves me cold. There is an elegance to the 12C that has not been surpassed. I own two 12C's just in case one is damaged! The Polish notation ('throw mother from the train a kiss' viz. 6, ENTER, 2, + {answer} 8 )is an eccentricity (like Uncle Fred's table manners) that is quickly embraced...a price for membership to the club. HP actually makes a version of the 12C that allows you to change this feature, but my guess is that it has never gained popularity.

    5-0 out of 5 stars You really don't need it
    I have had an HP 12C for 20 years.Yes it is wonderful calculator but you really shouldn't spend the extra money for it.

    It is expensive because it was designed for programming and elaborate cashflow analysis.Yes indeed in the early 80s people used to program 100+ step programs in to these dinky but powerful machines.Nobody would do it today. We have spreadsheets for that.

    The machine uses RPN (reverse Polish notation) so you have to get used to that, it has over 30 memories (I doubt you will ever use more than 3), the anachronistic programming capability and lots of funny symbols that I don't even know what they mean.My advice is to buy the HP B10.You can get it for half the price.Yeah its not quite the status symbol the 12C is but its all that you need.

    5-0 out of 5 stars I've had mine 20 years
    I've had my hp 20C for 20 years.Still works great.Still does everything I want it to.

    I'm stunned they still sell these things.Same design, same functionality, almost the same price (there were about $300 in 1985).What other piece of calculating electronics can claim the same thing?When these came out the Internet was called Arpa net, Personal computers came with 32k memory, floppies had 360k capacity, modems were 300 baud and nobody had "email".

    5-0 out of 5 stars READ with Mr. Tirone's HP-12C Real Estate Book
    I purchased this calculator some time ago but was not pleased with the manual's coverage of the field I am employed in, real estate. Then I noticed a real estate calculator book carried by by a Mr. John A. Tirone ("Professional Real Estate Problem Solving Using the HP-12C"). I purchased the Tirone HP-12C real estate calculator book from, best investment I have yet to make in real estate. The book is great--it covers so many topics in real estate that it is difficult to imagine a book of that level and quality being put together, especially when you take into account that the author supports his books.
    Nice calcuator, but Hewlett-Packard should consider including a copy of the Tirone book along with the device.

    5-0 out of 5 stars Best financial calculator ever
    I'm a gread student majoring in finance and I've owned a texas financial calculator for 2 years now.For some reason, I've never been able to master all the functions in the texas without keeping the instruction manual open.I finally decided to give the hp 12 c a try and am really thrilled with the results.The HP 12 c is very easy to master - took me 2 hours to go through the manual and understand everything and I dont carry the manual around anymore.Its made my life much simpler! ...

    5-0 out of 5 stars A word on documentation
    Recently received my Voyage 200, and am very pleased with the unit itself. As others have commented, the lack of a decent printed manual is a drawback.

    Knowing that the TI-89 Titanium is functionally almost identical to the Voyage 200, I called Texas Instruments and ordered a TI-89 manual. Customer service was very friendly, the manual was cheap ($4.95 + s/h), and it arrived quickly.

    TI really should package this manual with the Voyage 200, and maybe they'll start doing it in the future. In the meantime, if you're getting a Voyage 200, just order an 89 manual from TI.

    4-0 out of 5 stars Missing many statistic functions from TI-83
    Really good calculator, everything works good, and is really really fast for huge functions. As a statistics major, im a bit dissapointed, because this calculator is missing alot of the random functions the ti-83 had. Everything else good, great buy.

    4-0 out of 5 stars On a voyage.
    I've had this calculator for a year and a half and I must say it has served me well. Unfortunately, it just pooped out on me. I tried to use it one morning and it would not come on. All it did since the last time I used it was sit on my desk. No drops or anything. I changed batteries and tried all the troubleshooting suggestions on TI's website. Still nothing. I'm still waiting for a response to my emails that I sent two days ago to the TI Cares support.
    This thing was great while it lasted but now it looks like I'll have to get another one or maybe that newfangled TI-89 Titanium with the keyboard attachment.

    5-0 out of 5 stars Best calculator when you are on move
    I had long been an HP fan but Voyage change my perception about TI. When you use graphing calculator you don't need RPN notation. Voyage is one of the best calculator, with its large LCD screen and Qwerty keyboard you have much ease of entering any equation and it appears in the text book form. It does 2D polar plots, parametric plots, Direction fields and can plot in 3D besides solving differential equations of 1st and 2nd order. However its better to use Maple or Mathematica for 3D plots as they are much faster. It also has preloaded Statistics Package so it can do things like Hypothesis testing fot z test, t test, two sample test, chi square, Anova etc. An engineering package for Osculating circles, Rienmann sum, Curl, Divergence etc is also there, though I didn't find it of much help. However it has better algorithm than maple and mathematica for Double and Triple Integrals. If you are taking linear algebra then you can do things like eigen vectors and LU decomposition too, and with programming you can get Jacobian forms also. Good for Calc-I-II-III, Advanced Calculus and Dfeq.Upgrading software is a breeze with link cable and you have a access to a good application programs from TI to suit your need. Overall the calculator is neat, very intutive. It comes with a thin manual because you really don't need it.For other stuff you can visit their website or use the CD to look for any specific function

    5-0 out of 5 stars A great product
    The voyage 200 is the finest calculator that I have ever had. Its performance is remarkable and it is a user-friendly product. You do not have to remember in which button is the function that you need, or deal with buttons that have impressed three or more function in different colors. Just type the function and that is it. That is simple, is not it?

    It is also outstanding the main menu and its easy navigation. You can customize it by adding software applications from the texas instruments web page. The "Computer Algebra" application can solve equations, integrals and much more. "Organizer" mades a nice calendar to schedule activities, classes, and keep track of the important business of you life. "Notefolio" and "Cell sheet" are applications that work as interface for text and data between calculator and computer.

    The operative system can be downloaded to the calculator via USB cable with out problems. In conclusion, I believe that is a great product. Just be careful, so many features are not allowed in most of the standardized test and courses. ... Read more

    1-0 out of 5 stars Not a real HP

    I bought this calculator because I was afraid to lose my HP-15C while traveling.

    I really dont like the calculator because the butttons are oddly shaped and as a result they are difficult to press.Great action on the buttons is a hallmark of great HPs (15, 48, 11, 32, 42 ...)

    In addition the screen is difficult to read.

    I was glad when mine finally died for some unknown reason.I mailed it back to HPs CEO and she was fired the next week.So... maybe my letter had some effect.

    4-0 out of 5 stars HP 33s is on track but could use some improvement
    As an engineer, I can see the problems that HP is having in the marketplace with its calculator line.The desktop computer and math software has taken a big slice out of the top end calculator market, and what is nice about the HP 33s is that its positioned as a professional tool that can be used when more complicated math applications aren't needed.I have sold my older 48g and 49g models and don't plan on replacing them.

    My impressions of the 33s is that it is a good calculator.Most of the functions are very intuitive and the keys have a nice crisy feel to them.The sweeping keyboard pattern is very distinctive and the calculator itself is light but has a solid feel.However, the display can be difficult to read and the stack is limited to 4 lines.I am not sure how many lines the 32sII has, but it can't be any less and that calculator came out 20 years ago.Overall, I am happy with my purchase.

    2-0 out of 5 stars Disappointing Calculator
    I have used HP calculators since the very beginning in the early 70's.They were always the top scientific calculators until the early 90's.The best calculator for some time has been the TI-89.

    However, what strikes me about the HP 33S despite the difference in appearance and extra capabilities is how much it is like the old HP 15C which was a great calculator when it came out in the early 1980's.I am convinced that this calculator uses much of the same architecture as the HP 15C.I think they used the 15C design and simply made improvements.

    This is the problem with HP.I do not think they have been serious about calculator design for years.The HP 48 had serious design deficiencies (it was a lousy programming caclulator) and went for years without improvement.In fact the HP 42 of the late 80's was in many ways superior as a scientific calculator to this (the 33S), but for some reason was dropped.

    I could go on for pages about the deficiencies of the 33S but basically I think it is obsolete.It has good qualities but it simply is not much more than the HP 15C of twenty years ago.Personally, I am finished with HP calculators.Unless they recommit to calculators in a serious manner, I regard them as history.

    4-0 out of 5 stars Room for Improvement
    Don't like: (1) calculator buttons that click, (2) tiny decimal point, and (3) memorizing correction procedures for built-in HP errors caused by deficient quality control.

    After taking into account the above listed problems, the HP 33s is superior to TI-36X & Sharp EL-546V & Casio fx-115MS and is one of only a few calculators allowed with NCEES exams.

    I have owned various HP scientific and business calculators, including 28s, and the 33s is a couple steps down.Someday HP may regret neglecting what they once did better than any other company on the planet -- designing quality calculators.

    I was very nervous making this purchase.Unneccesarily so...the HP-33s is a good calculator with terrific value.The engineers and scientists who have applied their robust intellects at reviling this product are over-doing it.The small decimal point is indeed an issue, but as another reviewer pointed out, just use fixed-point notation and you'll be fine.If you can't see it, you're not working/studying in an environment with enough light. So do something about it, don't blame the calculator.This flaw should not deter anyone from purchasing this calculator, are anal-retentive and stubbornly and childishly fuss about details.Not saying it's wrong to be that way...just know yourself...if you're like that, then the decimal point issue will bug don't buy it.Seriously people, how many times are you going to be working with the number 2,222,222.2222?As for complaints about accuracy when working with complex numbers and random number generation etc...I only have an engineer's background in mathematics, but I know not to do hard-core calcs with a mere calculator, even an HP.If it's your final project or thesis, use a computer with Mathmatica or Excel or MATLAB.For people like me (studying for the PE), this calculator is a fresh update from the 32SII. HP could have done better, but didn't do THAT bad.I think some reviewers with a noticeably left brain tendency are focusing some frustration from their social lives on this poor innocent calculator. I would have reversed the direction of the that the 'V' shape was pointing toward the display, not down toward you.This better matches the natural configuration of your hands. It's well-built and lighter.It looks sexy...the same people complaining about the design are out of touch with current design trends and aesthetics...they've been trapped in the basements of post-mondernist, utilitarian technical schools or companies and haven't cracked a copy of Wallpaper* magazine or seen the latest line of Infiniti luxury automobiles.This calculator takes a step closer to being GUCCI and a step away from being GRANDPA.So much complaining about the colors...this is from people that probably haven't bought a fresh tie in years.A chick in the library or coffee shop might actually come over and pick it up and start talking to me. The signature HP characteristics are there:RPN capable (algebraic is bonus, but not really needed for me), clicking keys that offer clear assurances of crisp, definite key strokes, powerful features that attempt to meet the needs of everyday engineers, scientists and other technical practioners.They're trying to meet the requirements of a wide range of users. Of course, not any one group will be happy.The endless whining over the location of things like the ENTER button shows the silliness of some of the reviewers.How much complaining do people do when they buy a new cellphone and the menu button is different?It's not a big deal because you get a new cellphone like every year, unlike these guys who are probably still using their first calculators.I would have put the ENTER button next to the C button, but then you might accidently clear your registers, doh! At least switch the 0 and the '.' buttons, so that the numbers would match a phone keypad, which we all use and know. Anyone who knows really smart people, knows that they sometimes get worked up over little , nit-noid details.Think the guy from Office Space that was annoyed over the red stapler. If that is the case for you, then drop on a -48GX on ebay for $100, but if you want the 32SII with a new, slick exterior, then the -33S is for you. Don't listen to the haterz!For the record, I'm a HP vet with an -11C, -28S, -32SII, -48GX in my history. ... Read more

    3-0 out of 5 stars waste of money
    This calculator is a waste of money.If you need a graphing calculator, buy the 83+ or just the plain 84.The 84 is really bulky and not a real improvement on the 83+, the silver edition 84 is even worse - the white looks terrible, and the color face plates are even worse.If you're gonna buy an 84, you should just stick with the regular'll save some money and the blue looks better than the white.You're not getting anything more than what you'd get with the 84.

    5-0 out of 5 stars The best i have ever used
    This is the best calculator is the best i have ever used. It has a lot of great Apps. it has most of the basics for physics, chem, algebra I & II and a lot more. The keys are also very bright and easy to read. So if u r planning on buying a new graphing calc, go check this this out

    5-0 out of 5 stars Wonderful calculator, DON'T BUY A TI83
    I got a TI83plus but then it broke. That was probably the luckiest thing that could happen. This calculator is great!! Its fast, its pretty, and its really useful for school. DON'T EVEN LOOK AT THE TI83s BUY A TI-84-Plus Silver Edition Graphing Calculator ITS WORTH THE MONEY!!!!

    2-0 out of 5 stars TI-89 Titanium
    Ive used this calculator for awhile, then switching to the TI-89 Titanium I realized the TI-89 Titanium is in so many ways better then the TI-84 Plus Silver Edition. The TI-89 Titanium has a Symbolic Math Guide which will show you the answer and the steps it took to solve it. Either get a TI-89 or TI-89 TItanium!

    5-0 out of 5 stars I Loved It!!
    This calculator is great! If you download some of its applications, it can help you with almost all subjects in high school and some courses in college. You can share information with other calculators and recieve application information. It not only helps you with math courses, but with science and other courses. It's helping me, and it could help you too. ... Read more

    2-0 out of 5 stars Terrible Usability, I Don't Like
    Nice things about this calculator are it's good looks, simple interface, and price. But, maybe it's just too simple. Personally, I feel this calculator is not pleasant to use.

    1. Awkward viewing angle. The LCD is positioned such that you can view it only if your sitting back. Forget about looking straight down while solving problems. You'll be greeted by a terribly dim display.
    2. Button response is bad. For a $30 calculator, I expected the buttons to be at least decent. They're not. If you're like me, and are capable of quick entry (sometimes even with 2 hands) and enjoy responsive buttons, you'll be disappointed. The buttons are not firm to the touch and just feel cheap.
    3. Lacks slightly more advanced features. While the interface is easy to use and the basic features expected of a financial calculator are there, I think TI has room for some more. For example, there is no Option Pricing feature. That would have been great.

    For students (like me) who have worshipped the TI-8x's, the BAII is just horrible to even touch. Nonetheless, most people will find this calculator to be decent, at best. Really, don't expect any surprises, as this is as basic as it gets. For real value, perhaps invest a little more in an HP.

    4-0 out of 5 stars A first look at the New Look TIBA2+
    BA2+ users may like to know that Texas Instruments has released a "new look" TI BA2+ (allow me to call it it BA2+N), which may come with just more than cosmetic improvements over the popular BA2+.

    I was able to observed from a short distant away that the LCD display of the BA2+N,is clearer and more contrasty than the orginal BA2+ which I own. TI gets a thumbs up for doing this improvement quietly plus giving a facelift to this already highly regarded value for money business-financial electronic calculator.

    Although I have not yet been able to test the BA2+N, TI may have also incorporated some improvements and killed some bugs on the popular BA2+. It is also probable that some improvements or new functions incorporated on the September 2004 released BA2+ Professional (BA2+PRO) may also have been also incorporated into the specs of BA2+N.

    I would like to believe that some small but extremely annoying bugs of the "original" BA2+ has been quietly fixed on the BA2+N. In particular, I wish to see the "Reset" button nuisance which clears all user input formatting on the BA2+ has been done alway with. Most users of BA2+ would know that an accident user soft reset would return to the default Number of Periods per year P/Y to 12, this would upset the results of many TVM calculations when user has set the P/Y to "1" to use the calculator in "number of periods" instead.

    I was not able to exam a unit of the BA2+N to see if end users would still need a screw driver to unscrew and pry open the BA2+ casing just to replace the CR2032 battery. It would be nice if TI would incorporate a user accessible slide open battery compartment for the BA2+N or future upgrades of the BA2+.

    Would be buyers should get hold of the BA2+N or buy the BA2+PRO if you have a bigger budget. Budget conscious users could see that for the price of a BA2+ PRO, a screw driver and spare batteries, new users could afford to purchase for themselves two sets of BA2+N.

    An advantage of having a spare BA2+N set on hand is that users could free themselves from the trouble of carrying a philips screwdriver and replacement lithium batteries to important assignments or to the examination centre.

    HOW DIFFERENT DOES THE BA2+N LOOKS? I have downloaded the BA2+N JPEG picture from TI's calculator site and posted it to the Amazon's picture gallery.

    IMPORTANT NOTE:I have commented on the BA2+N as an end user and I don't work for TI, HP or any of the manufacturers for the products which I have used, reviewed and posted my comments on the pages of It is my pleasure to be able to share my first look at the BA2+N with you, thanks for reading!

    3-0 out of 5 stars CFA users Choose TI BAII Plus
    This review is directed toward those taking the CFA exams.The TI BA II plus calculator is more straight forward than the HP 12C for the range of questions asked on the CFA.The BA II Plus calculates faster than the HP, and is less expensive.

    If you need the button quality and durablity of the HP 12C unit, upgrade and buy the TI BA II Plus "professional" - this unit has a brushed aluminum case and buttons similar to a HP 12C and costs around $50 - similar to a HP 12C.

    When doing uneven cash flow problems the registers to the TI are all labeled so you can quickly enter data giving greater confidence with improved speed to your answers for NPV and IRR calculations.

    I still have two or three HP 12C's around, but they aren't as intuitive as the TI for the CFA Exam.If you are taking the exam - the TI is the way to go.

    3-0 out of 5 stars man, this thing's annoying
    If not for the fact that this calculator is required for the CFA i don't know why anyone would buy it.
    It takes many, many keystrokes to get simple things done, and let's face it, in the real world i'd much rather work out a complex NPV calculation in excel where i can see what i'm doing step by step rather than some arcane series of keystrokes where one mispressed key will screw everything up.
    Also, my unit suffered from poor battery life, which i assume is a manufacturing defect.
    A word of advice for students who can use a more advanced calculator: get a ti-83 or similar, learn to use it, and you'll be much happier. I find myself using the ti-83 i got in college rather than my financial calculator all the time.

    2-0 out of 5 stars Easy to make mistakes
    I got this calculator free on a financial course I am taking.It is easy to use but what others say about getting wrong answers seems to be down to the operator buttons on the right hand side being out of line with the main keypad.So you have to watch what you are doing.This and the fact it seems to take so many keypresses to get anything done makes it cumbersome.It is a reasonable calculator for starting out but I would not recommend it if you are in a hurry eg. sitting an exam. ...

    2-0 out of 5 stars Horrible "feel" and cheap case
    The buttons are horrible...I can't tell you how often I have to retype numbers because the calculator did not capture my input.The buttons have a "sticky" feel and are small.Also, the case is a cheap attempt to emulate the strength and durability of the HPs (I hate the 12C...but I think its design and durability has not yet been matched).

    3-0 out of 5 stars Slow Input
    This is a great calculator, but when you input numbers fast, they do not always register.If you buy this calculator, input 1,2,3,4,5,6,7,8, and 9 as fast as you can.You may encounter some numbers not registering even though you hear the number click (as if the number was added).This was not a problem with the BAII Plus.This is a huge disadvantage to this calculator.

    5-0 out of 5 stars Major improvement from BAII Plus
    Compared to BAII plus, it is much heavier with the metal cover. Too light is a disadvantage for the old model. Now, this one won't jump around when you punch the keys. The pros of HP 12C says that one is like a tank. This one is just like a samller tank, maybe.

    The display is another major improvement. The view is clear and won't change for different angle. This won't be a worry on your CFA exam.

    Keys are harder to punch; this is a bad feature for professionals. But it is not that bad as long as you can hear the "click", which is not that hard, the number will be there. People with less strength on their finger will complain too.

    Easier to change the battery, though you might worry it is too easy. Don't open the cap too often will help. The good news is you no longer need to carry around a skrew driver on you exam day, only the battery.

    4-0 out of 5 stars Great product, cheap case
    Just to clarify, this is a financial calculator, essentially the same calculator as the "Texas Instruments BA II Plus Advanced Financial Calculator" but with a cosmetic make-over.

    - Very attractive appearance.
    - Nice "firm-touch" keypad.
    - A couple of additional functions (compared to the BA II Plus Advanced).

    - Leatherette soft case instead of hard case.
    - Approx. $21 more (at time of writing) than BA II Plus Advanced.

    This is a very nice calculator.It is full-featured financial calculator with an attractive appearance.The brushed metal facehas a polished metal inset to highlight the primary financial function buttons. I like the button layout (which is the same on both the Professional and Advanced models), and preferred it over that of the HP 10bII financial calculator, which I thought had poorly-marked non-financial functions.

    The calculator has a solid feel that is consistent with its metal look, and that is further reinforced by the "firm-touch" keypad.Personally, I like the feel of the firm-touch keys and prefer it over a regular keypad, as is found on the BA II Plus Advanced.

    My one complaint about the BA II Plus Professional (and the reason I rated it as 4 stars instead of 5) is that it has a soft case instead of a hard case. While the soft case will help protect from superficial marring, it won't protect the calculator from impact or pressure damage, or from accidentally pressing buttons (such as "On") when carrying it.For the extra $21 more than the Advanced model, it would be nice if the Professional model came with a case that will actually protect it.

    - If you plan to keep your financial calculator around for a while or will use it a lot, and want something nice, then I would recommend this calculator. (I basically think of it as an investment in something I will continue to use for several years.)

    - If you think you would prefer a more firm-feeling keypad, then I would recommend this calculator.

    - If you are just buying a financial calculator for a finance class and don't plan on getting much use out of it afterward, and don't need the additional functions of the Professional version (which are advertised as being "Net Future Value (NFV), Modified Internal Rate of Return (MIRR), Modified Duration, Payback, and Discount Payback"), then I would recommend saving some bucks and getting the Advanced model of the BA II Plus.

    5-0 out of 5 stars Easily better than ANY current HP--and 1/2 the price!
    Have been a stalwart HP financial calculator user for over two decades...started with an HP41 in college with financial templates.I always admired HPs for the durable build, ease-of-use (once you got over the RPN hurdle) and displays.I finally needed to replace my over decade old HP 12C and the newer HPs simply do not impress me.Cheaper (as in WAY cheaper!) build...the HPs that came from Malaysia were fantastic calculators...solid keystrokes, superior grade of plastics, the whole nine yards.The newer HPs are made of a plastic that is a giant step backwards.The keys are now laughable, no 'HP Feel' to them at all.

    I took all of this in and thought to myself, 'I guess everything is getting cheaper, nowadays...'.Then I ran a NPV calculation at the store and was downright shocked to see it ran slower than my old HP.The one thing I thought MIGHT save the purchase (i.e. cheaper plastic but faster processor) didn't happen.I tried all of the newer HPs...the one display model of the OLDER HP12 (the non-Platinum model and still made in Malaysia) definitely runs TVM calculations quicker.This is NOT how to impress old bankers with a new product.

    Time to check out the Texas Instruments BA II Plus Professional.At first glance, to an old HP user, I thought it really LOOKED TI-ish; that is to say, very non-HP.But upon pressing a key or two, I was impressed that TI at least made an attempt at obtaining the old 'HP Feel' to their keys.Not as 'pretty' as HP's angled keys, but good tactile feedback and get this:If you'll hold up the TI BA II PP horizontally and sight down the keys, you'll see they are actually angled!Nice touch, TI.

    Nicely laid out TVM section (my only reason for owning a financial calculator, thus supremely important to me) and intuitive to boot.Speed of calculation simply SMOKES current HPs...there is absolutely NO CONTEST.A complex Internal Rate of Return took two to three seconds.TI hasn't been simply sitting around and 'repackaging' anything; whatever is under the hood of this calculator is current and fast.

    The rest of the calculator is nicely laid out...keys are pretty much TI convention, which to me is different.I miss a prominent ENTER key.

    Likes:I like TI's 'CHAIN' calculation mode.It's similar to RPN without the ENTER keystroke.Remember this if this is your first financial calculator:Most financial calculations are run in CHAIN or RPN mode (and, sadly, no, the TI doesn't support TRUE RPN), not the Algebraic Operation System (AOS).To TI's credit, the calculator defaults to CHAIN calculation (for newbies, this just means that the calculator runs the operation AS IT IS ENTERED; NOT following Algebraic heirarchy of operations).But it is nice that TI recognizes how financial people enter calculations and, unlike other TI calculators, AOS is NOT the default entry mode.

    Love the fact that the compounding rate is defaulted to 1, not 12 (HPs always default to 12).Love the fact that interest is always entered as a whole interest number (it divides it for you, automatically).Good, not great, manual.Battery access is very easy.Quality looks genuinely good, but time will be the only final arbiter on this one, but the product appears to be (in my highest compliment) equal to older HPs in every respect.

    Dislikes?Quibbling ones to be sure, but the compounding rate mentioned above is a pain to get too; I must have looked 30 minutes in the manual to finally find it (hint: you have to use the Down Arrow key to roll through a series of selections to get it...and it's NOT the first choice).Wish for (on all financial calculators, not just TI) normal AA or AAA batteries...why the manufacturers have to insist on the round, hearing aid style battery is beyond me.I mean, really, how big is a AAA battery?

    Wish TI would step up to the plate and offer some mortgage/realty functions in a financial calculator without forcing a user to own 2 calculators.Wish it were programmable, which is just a follow-on to the mortgage/realty/specialized functions.

    If TI offered this same model with enhanced functions, programmability and a normal battery, HP could give up the calculator market.

    As it stands, a worthy heir to the older HP calculators.I'm sorry to see HP cheapen the product so badly, but TI will gain market share on this one.A solid keeper. ... Read more

    4-0 out of 5 stars Excellent but user unfriendly
    THis machine does it all provided that you learn how to use it well. I spent quite some time on this calculator and I am very confident using it now. However it could have been more user friendly.

    5-0 out of 5 stars DO NOT BUY unless you are in calculus
    PUBLIC SERVICE ANNOUNCEMENT:This is a fabulous calculator (thus the five star rating), but inappropriate for students in math below calculus.Below calc, most courses that require a graphing calculator are geared towards the 83/84, so unless you are very comfortable with the 89 it may prove difficult to translate in-class activities onto an 89.Do not even THINK about buying this calculator unless you are taking calculus or a calculus-based course.Stick with the 83/84.

    5-0 out of 5 stars Sweet Calculator (For Calculus ETC)
    Awesome calculator. Last class I used it for was Calculus for Engineering I. I like the "pretty print" which will display equations exactly as you would right them. The calculus tools, and the resolution of the screen, and the ability to scroll through previous equations.

    My favorite T1 so far that I've used.

    5-0 out of 5 stars Essential for Calculus and beyond
    Once the essentials are learned in any field, its great to have a tool to do the busy work quickly.The Ti-89 calculator by Texas Instruments performs all the functions you'll need to do this busy work.Being able to use SmartText to display integrals, differentials, taylor series sums, etc. allow the user to clearly identify any mistakes.A lot of technology has been pumped into this little machine seeing as calculator programs are written using only the functions +-/X.There are many submenus's withen keys that are color coded for easy recognition as well as on-screen displays for menus.Dual menus are also handy for comparing graphs and calculations.Programming is a sinch with the instuction book and downloading programs is possible with the add-on cable.There are thousands upon thousands of programs written for math, economics, accounting, etc. that will allow the user to drastically expand the functionality of this calculator.5 Stars.

    5-0 out of 5 stars Great Calculator
    I bought this calculator after having used a TI-83+ for a few years. The power in this little machine is incredible (and in fact uses the same processor as the Macintosh Classic computer from 1991) and the display resolution is fabulous, especially compared to the older calculators. While I have yet to use some of its more advanced functions, the ones I've used have been great. Some of the functions from the TI-83 are moved and take a bit of adapting, but after a few weeks you'll love the menus so much you'll never want to use a TI-83 (or a regular scientific calculator) again. ...

    I am on my third TI-83+ (my first two were stolen).My brother owns an 84, and I can tell you that it offers nothing that the 83 doesn't have.Many of the preloaded apps are useless (an address book?please!), and take up so much space that the memory increase is worthless.The 84 is a continuation of TI's tendency to offer huge amounts of style with little or no substance.I prefer the 83 for its streamlined design.The one improvement is that the slip cover on the 84 does not become loose with a great deal of use, which is a problem I have encountered with my three 83s.It looks as though the USB connectivity could be a plus (for the 83, you had to buy a separate connectivity kit to connect to a PC), however, most buyers will not need to connect their calculator to their PC.

    5-0 out of 5 stars VERY helpful!
    Since I am in the higher math, I really needed a graphing calculator. So we saved up some money and got this.... and it helps so much! I don't really have anything to compare it too.... it is good for people in algebra and up though. and just fun to mess around with :D

    5-0 out of 5 stars Best School Supply Ever!
    This calculator is hands-down the best I have ever had the honor of using. While the TI-84 Plus may not have as much space or as many pre-loaded Apps as the TI-84 Plus Silver Edition, the TI-84 Plus offers everything a high school (possibly some college) math student needs in order to successfully learn and solve mathematics material. The TI-84 Plus comes loaded with several Apps that will make things even more convenient, such as a Probability Simulator and Cabri Jr., a great geometry app. Student looking to upgrade from the TI-83 Plus will find comfort in the fact that the TI-84 Plus is 2.5x faster and has 3x the memory than the TI-83 Plus. The TI-84 Plus is also extremely easy to hook up to your computer to transfer new Apps and updates to it using the USB port and the included USB cable. The TI-84 Plus will be a great investment for any student's education.

    5-0 out of 5 stars A great improvement on the TI-83 Plus
    The new TI-84 Plus is a wonderful calculator.If anybody has had the TI-83 or 83 Plus, they know how easy and reliable it is.The 84 Plus is an all-around imprivement on the older version and even worth the additional $15-$20.I have had it since school started and have noticed than any problem I enter, it is solved immediately upon pressing enter, or solve.The speed is a great improvement over the 83-Plus.The computer features are nice, but rarely used by myself.For anybody who is supposed to buy a TI series calculator for school, the 84 Plus us definitely the one to pick up this year and for the next few years I assume.Easy, fast, reliable, durable, and even sleek.As long as you handle it properly and use it enough, you will get all of your $110 out of the TI-84 Plus.

    5-0 out of 5 stars The Most Straightforward Calculator Available
    I have the TI-89 Titanium and the HP-49G+, both are excellent calculators especially for programmers.But if I need to have mathematical models/programs, I use Mathcad or Matlab on my PC anyway, hence, I don't use the TI-89T or HP-49G for that purpose. Although there are fancier/faster models available now, the elegant keypad and menu system of the TI-86 is unmatched.For me and for most people I know (mostly fellow engineers), the TI-86 (and HP-48GX) are the perennial favorites.There is a dramatic difference between the TI-86 and the TI-89 as far as the menu system goes.The TI-89 has so many functions that the only way to really implement it is through a "windows" type menu system.The TI-86 on the other hand, has all the critical functions on the keypad - which is more efficient.(i.e. x^2, 1/x, complex, convert, log, etc..... are all built-in to the keypad of TI-86).

    Indeed, the TI-89T and HP-49G+ are faster, has more functions, and has more memory than the TI-86.But for the day-to-day engineering and scientific calculations, I think the TI-86 is far more efficient and straightforward.

    3-0 out of 5 stars Best Graphing Design but problems with wear and tear.
    i am actually shopping for an HP49 or similar. My experience with two calculators from texas instrument the TI86 and TI83+ has been positive and actually excellent if ease of use and graphics performance is the criterions. They are very well designed and the graphics as of the last generation TI's were superior than there previous hp48g.
    However, the problem with both the TI86 and TI83+ is in how long they last. I bought a used TI86 in about 1997 and it lasted maybe one more year before it stopped working correctly. Recently a TI83+ I had which from the standpoint of functionality was a fine calculator stopped working after generally light use after 5 years. considering I used relatively infrequently, I wasn't satisfied.I used to own an early HP back in the 80's and it never stopped working for at least 6 or seven years until it was stolen out of my backpack. I was loyal then to them, but the last generation of calculators seemed to have some design flaws(hp48g) particularly around graphics. This generation seems to be immitating the TI's now and if they are built as well as the early ones, it is worth paying a little extra. But i haven't tried them out yet.
    The last one I had(48g) was stolen or lost somewhere I believe but it continued working fine for maybe two years.
    After spending onehundred plus dollars Iexpect more from a calculator in terms of wear and tear.

    5-0 out of 5 stars Very Useful calculator
    I bought this around mid 1997 and I'm still using it to this day.
    It's helped me through AP Calc, Calc II, Calc III, Differential Equations, Advanced Engineering Math, SATs, GREs, Fundamentals of Engineering exam for EIT certification, and etc...

    I actually bought a TI-89 around soph year of college just to complement the TI-86.

    You see, the TI-86 is a SOLID engineering calculator. It's got fast units conversions, an intuitive and FAST menu system BUT it lacks "pretty print", handling of units for math (keeps the units throughout equations, calculators), and integration/differentiation with the variables in place (it doesn't just evaluate it). With the right software, the TI-89 is a very powerful math tool.

    I used the TI-89 primarily for theoretical math but came in handy for standardized tests as well.

    I would recommend getting both the TI-89 and TI-86 and start familiarizing yourself with both calculators before you start tackling tests. Check the rules and regs for calculators also - standardized tests should allow the use of the 86 and 89.

    Overall, the TI-86 is a solid math tool - notice I say TOOL because that's what it is. If you have no idea what you're doing in class, the TI-86 won't give you an A.

    My recommendation is to get both the TI-86 and TI-89.
    Just FYI, I'm still using the TI-86 at work. The buttons show some wear and I lost the first line of the LCD because I dropped it in college. Nonetheless it's still chugging along.

    Also, slap in four 750mAH NiMH batteries. You will NOT regret this because these calculators drain alkaline batteries in half a semester of intensive use. We didn't have cheap NiMH batteries back in the day - TI actually pushed the use of Rayovac Renewals (remember those rechargeable alkalines that only lasted 5 charges?) and our other choice was NiCd. Forget all that. Slap in four Energizer 750mAh NiMH batteries and you'll save yourself a LOT of money in the long run. That means more money for video games and other forms of entertainment in college.

    5-0 out of 5 stars Need a calc for engineering work?
    Or require lots of fast unit conversions?

    Get the TI-86.

    It's menu system is extremely intuitive and easy to use. You can fire away units conversions and simple math w/o running into any problems. In Comparison, the TI-89 is more powerful, has a better CPU, and has more memory - but the TI-89 shines in its simplicity. It's quite powerful in the right hands and is more useful in the workplace. The TI-89 is more suited towards the classroom environment.

    I bought one of the very first TI-86's in 1997 and used it throughout high school, college, and a few graduate courses. I still carry it around at work because it's been a big help.

    I dropped it once and lost the first 2 lines on the LCD, but it's still chugging along fine.

    Just get 4 NiMH AAA batteries and you'll be fine for years to come. I made the mistake of using Alkalines, Rechargeable Alkalines, and NiCD batteries back in the late 90s when NiMH's weren't readily available.

    5-0 out of 5 stars You got to know whats up( From a programmer, I know. )
    I used to have a ti-83, and a ti-83+, but the 86 is the best of the three. I am real into programming the calculator. The 86 can have variables and Lbl's with up to 8 charectors, opposed to 2 for the 83, 83+. It can store almost unlimited amount of pics, unlike the 83,83+, which can only store 10. The calculator also does conversions. Everything from temp to energy to power, making it save all that time on tests and homework. I read another review that said it could not do absolute value(which is called abs), and convert fractions to decimals(>frac, and >dec), but it can. They aren't under a bunch of subfolders either, because you can easily create your own custom menu to paste anything you want on the screen. This way is even faster. It also comes with an excellent instructional manual. By far the best choice between 83, 83+, and 86. ... Read more

    5-0 out of 5 stars Fantastic product
    Despite the over-zealous negative reviews, I ordered this calculator and couldn't be happier!!! (I wonder if they work for the competition?)

    I am a business school student and originally started with the TI BA2 Plus, but was terribly disappointed, so I switched to a HP calculator based on the recommendation of two professors...I am so pleased that I did!

    This is a solid device and has not failed me in doing complex financial calculations.This is simply the best calculator I have used and I encourage anyone looking for a workhorse capable of doing long, intense calculations to buy it immediately!You won't be disappointed.

    3-0 out of 5 stars One more gripe
    Other reviewers have pointed out ways in which the 12cp falls short of the original 12c, so I won't repeat those.My gripe is that the case for the 12cp is complete crap.It's stiff and horrible.It takes considerable force to stuff the calculator into the case, whereas the old 12c case fits like a custom glove.

    1-0 out of 5 stars Very Disappointing....
    At first glance, this thing looks great.Nice, updated design, amdthe color looks good.But then there is the Enter key "bounce."The orange function lettering is almost impossible to read.Some of the TVM calculations are slower.

    It's great that they made the numbers on the display larger, but the display itself is DIMMER!Much harder to read in certain light conditions than the 12C.What were they thinking when they designed this thing???

    For $19.95 this device would be a good buy.But not at the $80 that I paid before I returned it.

    Do yourself a favor.Pass this one by and get the good, ol' 12C

    4-0 out of 5 stars 12C Platinum is Great!
    12C Platinum is way better than what the reviews say.It's classy looking and has RPN AND algebraic.My kid brother, who isn't too RPN, is already borrowing this.I keep stealing it back for its RPN features.HPjust needs to have these at the stores so that more people can view it, try it and buy it!

    5-0 out of 5 stars Supposed to be new, but was sent a used model

    5-0 out of 5 stars I love my TI-83!
    I bought this calculator when I started high school and I have not needed a new calculator since.It has served me well for 7 years and is still going strong.Perfect for everyday use and for any other use should you need its higher functions.I also find it very easy to use!

    5-0 out of 5 stars Like an old buddy...
    I have been using my TI-83 for over 6 years. It is the most reliable item I have ever purchased in my entire life. It construction is of very high quality: encased in durable, thick plastic with a highly readable screen and equally-sturdy plastic buttons, it does so many things, and does them well: graphing functions, programming support(similar to Assembly--fun!), probability and statistics options, an tons more that I haven't even explored. The instruction book is several hundred pages long and explains in excruciating detail what this baby does. The TI-83 is perfect, and just plain "feels right". This great indoorsman gives it a "must-buy" rating.

    5-0 out of 5 stars worth its weight in gold
    I'm in College Alegbra this semester and only starting to learn all the wonderful things that the TI-83 can do for you.With the TI-83 I feel so much more confident and it really shows in that my grades do improve.(It helps when you know the equations to do the problems with. ;-))I would definitely recommend this graphing calculator to anyone who needs it in college or in high school.It's invaluable.
    It's also good for those days when you simply can't study and need something to occupy your time with.Hint:Use the Program feature.In the past, I used it to go on trips with.Talk about a dual-purpose gameboy!
    I hope you enjoy your TI-83 as much as I did... er, do.I'm not giving it up that easy.

    5-0 out of 5 stars Great Calculator
    I first used this calculator in high school.I found it very useful in solving just about all types of mathematical problems.I've used it all throughout college and graduate school.It is very easy to use.It comes with a thick instructions book (very helpfull). Batteries last a very long time.I would also recommend the TI 83 PLUS calculator.

    Hewlett-Packard's HP 48GX is the most powerful calculator in the 48 series, offering the same advanced calculation and programmability features as its siblings, along with expansion options that should appeal to power users and programmers. All this is made possible by the expansion card slot, which lets users expand the built-in memory from 128 KB to a maximum of 1.256 MB or install application software that adds more advanced features to the calculator.

    The 48GX is no slouch. Its colorful array of buttons lets users tap into 2,300 built-in functions, 300 of which are built-in formulas and scientific constants that encompass the spectrum of the mathematical and scientific fields. It handles everything from basic algebra equations to advanced trigonometric and statistical calculations. Best of all, if the 48GX doesn't have a feature you desperately need, you can use the built-in object-oriented programming language to create functions from scratch. You can then label your creations and access them as you would any other feature that is integrated with the calculator.

    The 48GX uses reverse polish notation (RPN, also called postfix notation), which can be difficult for beginners to grasp, but advanced students and professionals will appreciate RPN's elegance and relative simplicity. An optional connectivity kit lets users connect the device to a PC to download new equations and software, and the integrated infrared port lets you share data with other calculators or output your graphs, plots, or other results to a separately available infrared printer. Typical students may want to opt for a less expensive (and less expandable) calculator in the 48 series, like the 48G+, but for those who demand the best and may need more than 128 KB of memory, the 48GX is the clear choice. --T.

    5-0 out of 5 stars Stack is different.This required learning
    To store '5' on the HP48 line of calculators, hit 5 [enter].It's stored.You can even see where it's stored right away because you're always looking at the bottom four stack entries.It seems the previous reviewer believes that the way TI does calculators is the way calculators should be done.If that's you, buy a TI.Storing a value in a named variable is a fundamentally different way of thinking about calculation from the way HP decided to do it.

    With RPN, there is very rarely any need for a named variable and it only took me about an hour to start using this calculator for fairly complex EE homework.One of the things I noticed about RPN fairly quickly is that if you're doing complex calculations, you'll often build up intermediate values and then bring the intermediate values together at the end.My study-buddies were always writing down their intermediate values, I just left them on the stack while I did the other calculations.More often than not, those previously calculated values were exactly where I needed them when I needed them later.Everyone else was punching back in the values that they had previously written down (with the possibility of error on each transcription) or trying to remember which variable they had stored them in.

    I don't mean to ding the TI approach, I used to work at TI and I think they make a great product.I simply think that the HP has a subtly better philosophy of calculation and a massively better keyboard in the 48s/sx/g/sx line of calculators.

    5-0 out of 5 stars The Mercedes Benz of Calculators
    Being a college professor of Electrical Engineering for over 30 years, and having used numerous brands and models of calculators and having written reviews of some of them for various publications, there is no doubt in my mind that the HP48GX is indeed head and shoulders above all the other calculators (even the HP49).The RPL entry system is a natural and easy to learn process that mimics the pencil and paper approach that we've all learned in Grammar school arithmetic.The efficiency of input and the ease with which it handles comlex-number calculations is second to none.Formulae can be entered with mixed units and the calculator automatically performs internal conversions to present the answer in whatever valid units you desire. It handles 2-D and 3-D vectors with all the corresponding mathematical operations seemlessly. The infrared connectivity (wireless) and RS232 port (wire) both allow communication between another HP calculator and your computer.This calculator has the right mix of 'function per key' versus 'menu per key' that makes it very easy to negotiate.
    One can enter a formula in algebraic notation and the calculator can solve for one of the variables in symbolic and/or numeric form (if all the other vales are specified). The keystroke error recovery facility is superb.A couple of days with this calculator and most people cannot go back to their old 'Algebraic Operating System' calculators, with its cumbersome parenthesis, without making a mistake.
    There is not enough space here to praise this calculator to the extent that it deserves.Over the years with all the students and professionals I've had contact with, I know of no one who has ever regretted purchasing this calculator except for the fact that they realized that they waisted money on purchasing their AOS calculators.

    5-0 out of 5 stars HP and RPN Entry
    Sorry if this is a little off the topic, but I guess you could say HP sent me here.....
    I own a somewhaz tired HP32SII...ands wanting to replace it, naturally, I looked at HP first as I did not want, nor have I ever needed an "Equals" key:-)

    What i found amazed me...not only is my 32SII worth about 400.00 dollars now, there are no more to be had...suddenly it doesn't look too tired!I continued to look for HP's RPN offerings, and found, other than the 48, they don't have any RPN Calculators anymore.I was told that they have something under development,due out in late Fall or early Winter.They did not say it was RPN, nor did they quote a "Ball Park" price, so I can't wait!

    Has HP lost its collective mind?Is anyone in HP product development or Sales following this discussion?I hope so.

    By the way, I paid around 45.00 dollars for my came with a great soft cover manual, about 160 pages, and is the best calculator I ever owned.It replaced my 70's era HP33E, which I still have.....Wonder what that is worth?

    Thanks for allowing me to vent!

    5-0 out of 5 stars PE = Paranoid Extremist
    This is without a doubt, the best calculator ever made for engineering calculations and tasks.Unlike a laptop, it never runs out of battery power in the middle of a design, can be used easily on a plane, can even be used in techincal customer meetings or on the shop floor to check things out that need checking.In an age of spreadsheets and complex analyis programs, it is often forgotten how useful a competent engineering calculator can be to a practicing engineer.It is also invaluable to students of engineering for assignments and exams.Speaking of which, the MN (and soon NCEES) policy has changed so that this calculator is no longer eligible for use on the PE or FE exams.This is due to its ability to transfer data to others, and that one can type text into it.Using the time functions of the calculator, and some personal time trials on the practice exams, I estimated that it would take the average test taker around 1 week to type in even a portion of the test with the limited alpha numeric capabilities of the keyboard, and then transmit it through infa-red to a waiting accomplice 3-4 ft away (given best transmition speed).You would almost certainly be spotted during this activity, and forced into some form of slave labor camp or fast food restaurant. As I am sure most of you considering purchasing this calculator are indeed planning this type of criminal intent, I must warn you that you better think twice because they are on to you.However, those rare, honest engineering and technical types with a minor amount of integrity that somehow leaked into their character could reward themselves (after passing the test using a slide rule, an abacus and some rocks) with a fine tool such as this calculator.They are getting harder and harder to find, so I would buy one while it is available. (The alternatives I have found so far for my upcoming test are kind of like trading a Land Rover for a skateboard).The add-on cartridge with the additional 670 equations, constants and tables needed for the PE exam is pretty good too but may soon require a special permit to own. ...

    This is the latest incarnation of a tool I've been using for a few years now.The more I use it, the more dependent I become.Provides quick, accurate answers to almost all shop problems & equations.The memory function is a little confusing at first, but practice makes perfect.Excellent tool, well worth the money.There's a pocket sized version available also, called the "Ultra Measure Master", also very handy. ...

    1-0 out of 5 stars Broken display turns calc into paperweight
    The display started to malfunction after about eight months. HP needs to make it more durable.

    1-0 out of 5 stars Poor execution of a good idea.
    Typical Chinese clumsiness and low quality. The on off button is too easily bumped to on, and the little sack they call a case is so tight it activates the on button.

    I cannot carry it in my pocket or briefcase without turning it on and depleting the batteries, so it sits in or on my desk. I leave it out, and no one will even steal it. Both of the two I have had were intermittant. The first one had the display die, but it was replaced under warranty. Wish they had given me a TI BA II+ instead. Wish I had bought one instead.

    1-0 out of 5 stars Far from the best
    I bought this caluclator about one year ago.At first it worked nicely.A few days ago I went to use it and the screen was not working correcly.Characters would not show up and basically it became instantly useless.

    I would not recommend this product or buy another HP calculator.For a calculator not to work correctly in such a short period oftime is in my opinion poor quality and HP's disregard for quality.

    By the way, this calculator was never abused in any way.It sat in a desk with the cover on.Definitely look elsewhere.

    3-0 out of 5 stars Nice calculator - when the screen works
    I've own this calculator for four years and have had to replace it twice in that time because the display keeps burning out.They always work really well for me when they're new, but after about 18 months they're toast.

    1-0 out of 5 stars Dissappointing quality and keypad
    I bought this calculator because I wanted a 12 digit display,comma separators for multiples of a thousand, and some standard financial functions, all in a form small enough to slip in a jacket pocket. I didn't find any other brand offering a calculator with these features and I thought that HP had a good reputation.

    I was very dissappointed. The keys required a lot of pressure to work and I often had to redo calculations because I had keyed too fast and one or more keys hadn't registered.

    Then after a year the screen stopped working properly. I was actually pleased about this because it meant that I could replace the calculator without feeling guilty!

    I'm afraid I would not recommend it to anyone. ... Read more
