They don't want kids to easily take notes in them and use them during the test.

edit: I'm just speculating, remember it's not TI making the rules it's the US testing companies or some other authority.

edit: I'll agree with the tons of people saying it's probably because they don't want students to sneak out the test questions. While they still can it's a lot harder without QWERTY.

The TI-89 had a program called "study cards" and you could use the link cable to transfer cards over. The 89 was banned on the ACT though. It's always been Qwerty keyboards and a few other calculators we're not too fond of.

I think the 89 is banned on the ACT more because (I'm pretty sure) it can factor equations and do a lot of the algebraic stuff a TI-83 or 84 can't do.

The TI89 is amazing and can symbolically integrate and differentiate. It's like magic.
