Which calculator should I buy? The TI-89 Titanium or the TI-Nspire CAS?

Question

I am currently in my senior year of high school, going into AP Calculus AB. Which calculator would be best?

Answer 1

TI- 89 Titanium

I've got the TI-89 plus silver edition.  

and love it.

but maybe you should talk to your teacher, because i'm in AP Calculus AB but i'm not upgrading

Answer 2

The nSpire non-CAS is only slightly more expensive than the TI-89T, however the CAS version is even more expensive than the non-CAS.

I love my nSpire, and have used the TI-89 before. I would recommend the nSpire over TI-89 any day. With their new OS upgrade (http://tiwizard.com/page.php?id=4), the nSpire got even better with new improved visuals and features.

Get the nSpire, it is new (more likley to have OS upgrades, plus the upgrades don't delete everything in your memory), and it is cool looking. It is a great calculator to show off, and more powerful than the TI-89T when you know how to use it.

Answer 3

Can never go wrong with a TI :)

I'd say the TI-89 Titanium.
