Beautiful instrument, will do pretty much anythng you want
7 of 7 found this helpful Bought it for a differential equations class. It has served me well.
Advise: I would consider how far you are going in math before you buy it though. If you are not going very far the fact that no one can help you is very off putting when a TI-84 and 89 will do just fine. But if you are going for the long haul the investment is worth the initial suffering because this calculator is really the best model that I have found. It excels at virtually everything.
Bad: It's so fancy that no one else can help you do things with it. Usually google and the Texas instruments website is all you need though. It is also so good, that teachers usually do not allow it to be used on tests for Calculus and below.
Good: Great rechargeable battery, I dim the display to the lowest setting and it lasts at least a week (I use it virtually all day).
It can handle variable input, putting in x+y doesn't phase it, while the non-CAS nspire cannot accept undefined
variables.
It can graph anything I ask it to (3D included) and the screen resolution is great. Color screen is definitely better than the Ti 84 and 89 display.
Can be programmed to do almost anything but I am having trouble figuring it out.
Has a touch-pad mouse and many keys and operations are done like a standard keyboard computer.
It really is like a little computer and the only thing that I have found that gives it trouble are slope fields. The calculator does them just fine but while they are being displayed most other operations are slowed.

Works well
I paid for it but was afraid to swap it out until I did some research. It sat for about 4 months in packaging until recently.
The drive is working fine a month after I put it in and I have been using it every day.
Make sure to back up your files and programs as well as record your windows product key. I went to a computer help place and they had a copy of Windows 10 OS that they loaded on the computer to boot it up.
I needed to go through a few steps and I'm glad the place walked me through it. Make sure you know what you're doing or have help before you rip out your original drive.
