I think this is the best graphing calculator available - in my view better than the TI Nspire, Casio or Numworks competitor products and better value for money given that the competitors cost around the same as the HP Prime. Although it is a HP calculator, it's not one of their traditional RPN calculators - it does have a RPN mode, but that's quite limited. On the other hand, the HP Prime feels very well built and retains the classic keyboard layout and feel of older HP calculators - and has the added benefits that it's slimmer than most of its competitors and also has a lithium-ion rechargeable battery rather than using disposable batteries.There are, however, a couple of negatives regarding packaging and contents.The calculator comes in a near impenetrable plastic "bubble pack" that is almost guaranteed to injure the customer as they try to cut it open in order to extract the contents (check out the Youtube unboxing videos :) - I wish calculator manufacturers would go back to using sturdy cardboard boxes, particularly for top end calulators like the HP Prime (there's enough plastic polluting the world without HP and others adding to it unneccessarily).Once you do get the packaging open, you will find the calculator, a couple of cables (one data/charging cable and one for connecting your HP Prime to another HP Prime) and a few scraps of paperwork - but that's it, there's no decent case (just the hard plastic slide-on cover), no charger and no printed manual (both my previous HP calculators came with a strong vinyl case, charger and detailed printed manuals, and I at least would have been prepared to pay an extra £15-£20 to have a case and proper printed manual included). As far as the charger is concerned, this appears to yet again be a case of a US company subsidising their home market at the cost of overseas markets, because the HP Prime costs much the same on US stores as it does on UK stores, yet the US models come complete with a travel charger with a set of interchangeable international plug heads in the pack.As a quick summary, the HP Prime is an advanced graphing calculator with a colour touch screen (the only one out there currently) and a number of built-in apps offering such things as 3D graphing and spreadsheets. The graphing capabilities are fantastic, 2D graphs are drawn pretty much instantaneously and even 3D graphs are rapidly drawn - and uniquely, touch gestures can be used to move around a graph or zoom in/out.As mentioned previously, the HP Prime only has limited RPN capabilities and is primarily an algebraic calculator (although that doesn't really do it justice). In the Home view it works pretty much like a standard algebraic scientific calculator, but in the CAS (Computer Algebraic System) view, it performs symbolic calculations - and this works with anything from simple arithmetic like fractions all the way up to trigonometric and calculus functions etc.Most importantly, for me, the HP Prime is programmable and it's capabilities are made all the more useful because it has a very fast ARM CPU (for a hand-held calculator anyway). It is programmed using HP PPL (which is based on Pascal I believe) and although I have seen quite a few criticisms of HP PPL compared to HP RPL or Python, I've found HP PPL to be easy to learn and functionally rich. I would like to be able to write programs using more efficient low-level code, or have access to a true compiler, but compared to older calculators programs on the HP Prime still run lightning fast.It will take a long time for me to become familiar with all of its features (if I ever do), but so far I'm very happy with the HP Prime. Although, on that topic, I'd advise you to download both the original and the latest PDF user guides, because there are some commands (e.g. the IFTE command) that are missing from the latest user guide but are described in the older guide.This was a very brief review, and I'd encourage people to look at the in-depth reviews of the HP Prime available on the Web to see if it will meet their needs - but make sure you look at the most recent reviews as the older ones are based on the G1 version of the HP Prime with older firmware and therefore often mention limitations that are no longer present with the G2 version and the latest firmware.

I am a long time user of the RPN and RPL calculators and mainly use the 42s 48gx and 50g.My initial impressions of the HP Prime are good. It was very easy to pick up the programming language and if I'm honest, it's probably just as easy to learn as RPL. I was able to write a couple of programs on my first day using it.RPN mode is tacked on to this calculator and feels kind of pointless, if you are going to use the Prime you may as well take a deep breath and embrace the infix notation. A real shame because postfix was always a big draw for me with HP calculators and why I stuck with them over the competition.There are shortcuts everywhere on this calculator,what initially felt very foreign quickly became easy as I figured out how to drive it. The equation templates and operator shortcuts are really good, they make for a nice user interface and provide access to so much functionality quickly.You can't create user soft menus which is a shame, I really liked having folders and programs in the soft menus but you can create user defined functions and variables easily and access them quickly enough.Connectivity kit is very useful, you can create programs on your computer while debugging and testing them on the fly on the calculator. The latest firmware installed without a hitch on my MacBook Pro too.I miss a lot of functionality of the 50g but I feel like this is probably just temporary while I become more fluent in the Prime way of doing things.The hardware is a huge leap forward, not just for HP, but for calculators in general. It blows the 50g away with better buttons, fantastic display and a nice slim build. The plastic case is dreadful though, the calculator rattles around in when it's attached, both on the front and back. I saw a lot of complaints about the screen viewing angles which was a major concern. Either this has been fixed or they were greatly exaggerated. One thing though, the orange text on a white background is super difficult to see, even on the latest revision.The Prime is so far removed from the previous HP calculators, it is closer to a Casio or TI calculator than it's own ancestors. This is a shame really and I hope the next HP calculator is Prime like hardware and build quality with full RPL functionality and programming. It will be really sad to see the software, knowledge and experience gained using the 48 and 50g series become obsolete with the hardware.With all that said, I think this is probably the best currently produced graphing calculator on the market and a testiment to the hard work put in by the HP caluclator team. It also reminded me to pick up another new 50g while I still can.

The good.The HP Prime G2 is an exceptionally good calculator with more capability than I will even need. It supports both infix and postfix (RPN), however the postfix is limited as to where it is available, infix is available everywhere, there's also the algebraic CAS mode. The calculator performance is excellent and so is the touch screen. The rechargeable battery is replacable so when it finally wears out replacement will be possible. Two cables are supplied, one for USB pc to calculator connection and a second for calculator to calculator connection. In PC mode you can screen capture the calculator's with the free HP software. You can also download the PC calculator emulator and the 600 plus page manual as a PDF.Overall battery life is acceptable but you'll definitely want to carry a standard USB charger with you. The keys are excellent and those familiar with previous older HP calculators will not be disappointed.The not so good.The packaging, it's a heavy duty seam-welded blisterpack made from thick industrial strength plastic. It's an absolute nightmare to open. Even once you open it, the calculator is almost impossible to remove from the packaging. Be sure to take your time to avoid damaging the calculator. One minor niggle is the sliding cover is difficult to remove. The viewing angle of the screen is not as good as it could be but it's OK.Be aware.The battery life is OK but the screen does tend to eat power. Updating the calculators operating system should only be done with a fully charged battery and I found the update to be unintuitive. No official HP charger is supplied so use a decent quality USB charging adaptor, avoid the cheap ones to minimise any risk of damaging the device. I would suggest one from a decent brand mobile phone, not a £5 bargain basement one from a no-name company.Over all it's not cheap but it's worth the money.

quite a well thought out calculator. RPN (the main reason anyone used to buy a HP calculator) isn't implemented throughout the design which is disappointing. How and when you can use it isn't explained at all well so unless you are prepared to experiment, you may give up on it except for the most basic calculator work. I suspect the main reason for this is the difficulty of writing an editor to display entries made in RPN as text book (that or the power consumed whilst continually updating the display). Perhaps in future?something that seems to have gone is the ability to display vector fields that the HP49 or HP50 could do.I'll be hanging on to mine for that reason.the calculator also implements units so that you can be sure that the answers you get are suitably dimensioned, and scaled. unfortunately, that seems to be a half measure that will only help in the simplest of circumstances. functions (including equations) don't seem to have the facility to handle dimensioned parameters so the advantages of units are completely lost here.plotting complicated equations such as maxwell's distribution suffers from some issues. the default ranges just don't do the job and you have to put quite a bit of work in to establish sensible values (or have a very good idea what to use to start with).This calculator is, not surprisingly, hard on the battery. If you use it regularly, expect to be charging it up a lot. If not, be aware you may need to charge it up before you use it as it doesn't seem to hold its charge for more than a few weeks.if it weren't for these niggles, i'd love it. it's easy to see how useful it can be for exploring maths as long as you don't push it too hard or wander too far from the curriculum. within those bounds, it's utterly superb.

This is the best graphing calculator out there. Especially when considering the price. I manged to get it for £115 which is around £30 cheaper than the overrated TI Nspires. It's speed is unparalleled. It's hardware specifications are second to none. The build quality, oh my goodness, is absolutely solid unlike the Nspires whose buttons individually rattle for example.In response to Alexander's recent post questioning the Prime G2's graphing capability. Bottom line she is wrong. The calculator will plot the function she used as an example correctly, but you just need to present the equation in a slightly different way. Instead of plotting y=x^(2/3), plot y= 3rd root (x^2)and the graph is presented exactly as expected. Just don't have fractional exponents.The programming is very intuitive and when used with the HP connectivity kit (free download from HP) it is very easy to use. I frequently also use the free virtual version of this calculator to test things out before I transfer it to the calculator itself.The touchscreen I thought was a bit gimmicky at first but since using it, it has become second nature. I would hate going back to a non touchscreen calculator now.So happy with this purchase which replaced my trusty TI-85 from 1996. The leap forward in capability from that to this is astonishing.The ONLY reason not to get this is because exams do not allow it. But having said that, double check if the exam mode on this is sufficient to be allowed to use it as it can disable the CAS functionality.

What a beast of a calculator. After fixing the common battery issue these calculators have when new. It now charges and holds its juice for 8 hours plus with heavy use.(Running hypothetical what ifs the whole time) I am using lower screen brightness then factory default though. (Optionally get a 2100mah Galaxy S3 battery for even longer life.)Unlike some programmable calculators this machines language is a doddle relying heavily on a simplified version of Pascal.It even comes with a emulator for the PC, and connectivity kit. It is possible to edit your programs with the PC and save to the calculator. Sadly the calculator doesn't have qwerty layout. So this is a handy feature. Does it do all I want sure.It works out all the possible gear ratios with given shaft distance in a blink of an eye. It can even draw gear geometry. Oil pressure at a certain RPM and so on and on.... Obviously I'm only using the engineering part of it. But it mostly boils down to can you think it more then Likely it can calculate it for you.Only downer what on earth is up with the packaging needed some proper industrial scissors to get into it. Defo not frustration free. And possibly battery life it needs a charge at least once a week. Versus some.calculaters you can't remember when you put a battery in. Flip side though the speed and flexibility makes more then up for it.

I was looking for a calculator allowed during the IB Diploma exams and came upon this one. It features a much more modern design compared to other calculators and a better display witch touchscreen. It makes using the calculator really easy. The best thing about this calculator is the ability to turn on the exam mode and disable certain features. This allows the calculator to have many more features compared to other IB calculators (CAS etc.) which would normally be prohibited and it costs the same price. Using the HP Connectivity Kit on my Mac I was also able to update the firmware of the calculator and all of sudden new 3D graphing app appeared which was a great surprise.It is also really easy to download apps for the internet and load them on it. The build quality is also excellent and the included help menu for every function is great. The only downside of the calculator is that the battery percentage is shown in increments of 25% so you never really know how much exactly of the battery is left.Overall I would recommend this calculator as the best IB approved calculator you can get. When I showed it to my friend three of them already upgraded their calculators to the HP Prime.

Has the functions I need with a substantial speed increase.I had a HP 50G before and some lesser models TI-36Pro, various Casio models, also TI 83plus.Liked my 50G and RPN mode, but I’m versatile with calculation entry methods.The HP Prime so far has been good, and easy to update thanks to the connect software (for Pc or Mac).It updated so much easier than my 50G.It calculates so much faster. The colour is nice to have, so is the touch. I have a screen protector on my Prime.The battery has lasted well, though I don’t use everyday.The cover is stiff to slide off, comforting but also annoying. Would like a pouch like the 50G but maybe not leather.Would recommend for those needing the functions and versatility of this type of calculator.There is help on the internet,both on YouTube and various HP calculator sites.There is free HP Prime version for the Mac and PC that can also connect to the connect software.So try before you buy, then decide. I don’t think you can print from this calculator though.This is the G2 version I have.

This calculator is aimed at the same market as the TI-NSpire range, but covers the ground so much better and is blindingly fast at doing it.Its strengths are the internal mathematical function commands which are far more extensive than the TI -Nspire. The Matrix commands are more extensive for example and the programming language commands for things like drawing are very high level, dealing with objects rather than pixels. Whereas the TI-Nspire does not even have a 'draw' command. The only weakness I can see in the Prime are the lack of 3D graphing off the shelf, but this has been remedied by the 3D graphing application from a user.All in all this is a classy super-calculator with a refined touch (important for giving you confidence).Its newness on the market means that there are less user written 'apps' for the beast, but I predict that because of the emphasis on a strong internal commands which can be used in user programmes, this calculator will win the day. There I did not mention RPN once...ooops

I have always shied away from HP calculators due to their use of RPN input; I like to input as it is written (old school (literally))However I was really taken by the look of this calculator and impressed by the vast array of functions (or 'apps')Then I read that the RPN was, in fact, optional and not even set as the default; that being 'textbook'; ie just as it is written; ie just as I like itNeedless to say I immediately logged on to Amazon and had it 'express' delivered and it arrived next dayI can only say it is everything I expected, and then some; it is a truely awsome machine, unbelieveably quick and extremely complex (not complicated) so I will probably spend days, weeks,months investigating its many functionsHighly recommended

I got this for vector calcualtions and complex numbers for high frequency electronics, it handles it all well, although funilly enough the common complex actions e.g. complex to vector / polar etc is not so simple as I expected, I ended up writing some functions for it. The functions are great but having done a few I had to re-do them to organise things better. Given you can greate functions and apps yourself or get shred ones from the internet, this custmises however you like. Of course you can download this for PCs and so oddly I end up using the PC version most, and when programming I use the PC with the calcualtor plugged in and transfer the programs to the calcualtor after testing on thecomputer.

Latest HP calc, just starting to learn it all. Downloaded the full manual, 616 pages, and printed it off as a whacking great A5 book , as on-line or on screen just doesn't work for me. Very good graphing, starting to grasp HP PPL programming. as I am of the RPN camp from a HP41 CV.Very good screenWoud prefer it if you could make your own apps, linked to a program, not modified aliases of fixed apps. Finite variable names, some pre-assigned, eg M = matrix, V= vector etc.I suspect that even the manual is not the full story and a function reference manual is needed.

I've tried the Nspire CX CAS calculator and the HP Prime before purchasing. You can get a free version for Android, but I'm not exactly allowed to use my smartphone during quizzes, tests, and exams. I'm pursuing a degree in traditional mathematics. So, I have a variety of maths to work with.I've found the HP Prime to be much easier and more intuitive to use than the Nspire CX CAS.I went for the G2 because of the improved hardware, and while I'm in the US, there is nothing about this UK model that makes it any different in use.

This is an awesome calculator. I love the input methods and how the touch screen helps, love how the maths is laid out in a natural format, love the graphing features that enable me to quickly visualise results, love the computer algebra system.But there is one glaring issue... it seems the display is either upside down or you've put the wrong model in because the viewing angle is much better when you turn the calculator upside down! Come on HP! Where's your engineering quality control?!

I use the calculator for personal investigations and classroom activities.I suppose it's the outstanding help for doing good mathematics in a school!You can explore math concepts with Dynamic Geometry, CAS, Advanced Graphing, and spreadsheet applications. Easily switch between symbolic, graphical, and numerical table views with dedicated buttons.I hope some new apps will be added (parametricplot 3D, time and alarm facilities...).Wonderful product!!
