Title: A classic
Review: I can't believe it's already been ten years since I bought this (slightly used) beast at the recommendation of my precalc teacher (Thanks, Mr. Fischer, for the great recommendation, and not so much for the C I still ended up getting). After tagging along with me through most of high school, several different colleges and soon grad school, my TI-89 has worked, and still works, flawlessly. I keep up fairly religiously with most tech gadgets, but not when it comes to personal/academic calculators - I've never needed one better, and probably never will. It's powerful enough to satisfy all but the students of the most esoteric mathematics, and sturdy enough to tolerate constant abuse of a typical college boy's lifestyle for years. One of the highest quality products I've ever owned.
