Wonderful graphing calculator, more features than I could possibly use.

Awesome device and has a ton of great features that make it easy to use.

I have owned several TI calculators and while the features are great, but the the workmanship has gone down over the years.

The features on this thing is just amazing!

However, if Texas Instruments ever makes a calculator that combines the good features of Nspire CX CAS and the TI-89 Titanium, I will buy that calculator.

As a final note I just want to say that this is a very feature-rich and complex calculator

Maybe one of the coolest features is the ability to have spreadsheets and documents on it, allowing one to store important formulas and equations

It is possible that add-on apps improve some of these details so that I can do polar and parametric area, arc length and volume rotations easily, or perhaps the features are already there and just hard to access.

Another nice feature is the long battery life the calculator has

The n-spire is so much faster than the 89 at everything, and the addition of the touchpad (completely optional to use) makes many features like analyzing graphs much simpler

Nice screen, excellent features

Intuitive features were well organized and easy to learn.

Love the re-chargable battery feature.

Copying and pasting chunks of old calculations is another handy feature

This machine is as great as I needed it to be

It also has a faster processor, from what I've read as well as from experience with both calculators

n’t know if it works
