Re: While we're on the subject of TI...
I have the same TI-89 that I (got my parents to) bought when I was in high school. Even for 1999 it had a slow, outdated processor; today it's absolutely stone-age compared to a modern smartphone.
Anyway, this overpriced clunky monopolized chunk of ugly black plastic, dim puke-grey screen and obscurely confusing interface, got me through two years of high school, 4 years of college, and 10 years of molecular genetics and it still works just as well right now where it is a permanent feature of my desk.
That's why people buy TI graphing calculators, aside from all the superficially horrible overpriced features they are in fact extremely useful general purpose mathematical tools.
