Hp 2AP18AA#ABA Prime Graphing Calculator Ii

Nice product

De nombreuses fonctionnalités comme une partie de la concurrence. En revanche, au niveau rapidité de calcul, elle est incomparable avec le reste de l'offre. Un effort particulier a été fait sur l'ergonomie avec notamment l'aide en ligne. Le seul défaut assez surprenant est la très mauvaise visibilité des caractères oranges sur le clavier, pourquoi ne pas avoir opté pour du rouge par exemple.

I couldn’t be happier about my choice! It’s obviously an extremely powerful calculator, but what I love the most about it is how intuitive it is. The touch screen makes it so convenient to use — any possible symbols you might need for your calculations are just a tap away I did have quite some trouble updating it via connectivity kit on a MacBook, but it somehow worked after many failed attempts, and everything is perfect now I really recommend it!

Funkcjonalność jest ok, ale wskutek tego że bardzo często podczas obliczeń nagle resetuje się do zera tracąc wszystkie dane, programy i zmienne które sam stworzyłem, uważam że można traktować go tylko jako drogą zabawkę. Owszem jest coś takiego jak backup, ale trzeba by to robić co chwilę bo nie wiadomo kiedy się wysypie. Zmiana softu jic nie daje.

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 love how nice this calculator is and how it can do everything.
