When is a TI-89 ever needed/useful?

A TI-89 is totally unnecessary for AP calculus. I used my TI-82 (that I bought used on ebay 5 years ago) for the entire class but borrowed an old TI-83 Silver for the BC exam.

In the calculator part of the AP exam I think I used the calculus function only a couple of times. Most of the calculator portion can still be solved by hand. The only calculus help the calculator can really provide is to save a good amount of time on the couple of long definite integrals in the exam. But those can be solved even on an TI-82.
