Awesome calculator, I love the touch pad and the color screen

Nice screen, excellent features

Light, small, good screen and lots of power

Pros: MathPrint Input, fast processor, documents, bright color screen, lots of memory, full keyboard, battery life (about 2 weeks with heavy use)Cons

You will get many hours of use before you have to re-charge the battery and even when you do it is quick -- the calculator is also smart about conserving energy and it will dim the screen and then turn off if left to idle for a while

I had to replace my TI-89 and this has all the same features plus a ton more functionality and updated hardware like a touch pad and colored screen (especially useful for having multiple graphs up at the same time)

It also takes several steps to clear the screen instead of just putting a clear button on there

Compared to my TI-89 this is way easier to use, and thank goodness it has such a bright wonderful screen

Many other reviewers mention their screen getting scratches or smudges -- the screen protector will make that a non-issue for you

Its durable and has a great screen

The screen is very easy to read and identify the graphs as well as the solutions

The n spire, it is easier to enter complex formulas and the screen is nice
