After doing a hell of a lot of research on graphing calculators, and also having a bit of experience with Wolfram Mathematica and Desmos, I decided to purchase this calculator. I'm not going to lie, I was very nervous in making such a large investment in a graphing calculator. And it wasn't exactly aided by the fact that a desktop (with the right software) and the Desmos mobile app could do everything a TI calculator could do and so much more and so much faster. Would this graphing calculator also be a waste of money, even with its CAS?
Well, after using it for about a month, let me just put it this way. Mathematica may be a mathematical beast, but learning it is VERY akin to learning an entire programming language, so the learning curve is very steep. The freeform input makes it better for sure, but even then, that won't handle everything, and sooner or later, you're going to have to take the time to really learn the language.
Desmos is light and powerful. It will graph anything in a second and do simple calculations as well. It's also dead easy to use. Type in a function or list and boom, you got a graph. It will of course also tell you precise x and y intercept locations and other intercept locations (with one or two exceptions). But... Therein lies the issue. That's all it really does. No CAS. No anything else. Oh, and no saving functions or really anything whatsoever without an online account. (Booo... )
This is why, at the end of the day, the HP Prime (especially the G2) is still worth its weight in gold, even though graphing calculators are quickly becoming obsolete. Not only can it do almost everything Mathematica does (seriously, in terms of features, it's like having Mathematica Lite in your pocket), it's also very intuitive. You don't need to learn an entire language to use it. Unless you want to! The HP Prime is also completely programmable just like the TI calculators. And even further, it even allows you to write in super quick functions without ever having to touch the editor, and it will check the code for you right on the calculator.
I could go on and on and on, but I don't want to sound like some television commercial so I'm just gonna stop here, but I really can't say enough how impressed I am with this piece of tech, not only as just another graphing calculator, but as a general mathematical tool, period. HP KNEW their stuff when they made this calculator.
So is there anything bad about it at all? Unfortunately, yes. The biggest issue by far is that, if you mistype in a command or equation for it to work on, more often than not, it will fail and NOT EVEN TELL YOU WHY. Even the TI calculators will tell you where it went wrong. Now don't get me wrong. Sometimes the error message is descriptive and there's no issue, but it seems like a 50/50 thing. In that vein, it also has an idiosyncrasy of sometimes needing "4*x" instead of just allowing you to put in "4x". The (very) good news is that the HP Prime has a built in Help system that, most of the time, will get you out of your particular issue.
Beyond all that though, if you're going into any sort of advanced math subject at all or if you really need a light and easy-to-use version of Mathematica, then get this calculator. Hands down. It's definitely nuclear overkill for anything in High School or lower, but anything else... Worth it.

The next step, with color touch screen!2020年3月11日 - 已在美国亚马逊上发表
The HP Prime is an excellent scientific graphing calculator, featuring a rewritten operating system based on Pascal and Algol. It is an upgrade to the algebraic line of HP Graphers, but also includes an integrated RPN entry system. This is the finished version of what Bernard Parisse and the MetaKernel team started with the HP 39gII. Very nice tool!
Beware! Seller Did Not Disclose That Product Was Used2020年5月24日 - 已在美国亚马逊上发表
I love the features of this calculator and couldn't have been happier with it when it arrived. Then I tried to register the warranty and found that it had already been registered - so it was USED!. Then the calculator quit working. I returned it. I think the product is fine but I can not recommend buying from this seller.
calculator lock up issue2020年6月2日 - 已在美国亚马逊上发表
I attempted to update the firmware by downloading the connectivity software from HP's website. The software did not recognize the calculator at all. Instead it placed the calc in "recovery mode V13", the calc was bricked. I had to perform a master reset which caused the loss of all programs and data. This was not a one-time event, but repeated attempts also failed. On another long time irritation, the spreadsheet app does not accept date input. I have been using HP since the HP-35, but my recco to high level calc users is to simply get a TI-89 and be done with it. BTW the connectivity kit also crashed my system. Good luck.
This is the newer G2 version. Truly amazing calculator,2020年2月22日 - 已在美国亚马逊上发表
This calculator is amazing. Coming from years of TI calculators I was expecting a steep learning curve, but it’s fairly intuitive to use and the documentation available is more than adequate. I absolutely love this calculator, it’s speed, power and functions blow everything else away.
