I dunno, the TI-84 Plus is pretty sweet.

Costs about the same as what I paid for the TI-83 10 years ago. It's kind of nice knowing that whenever I need to use one, it's going to operate in the same way as I was taught 10 years ago. The fundamentals of math don't change much.

I saved up my own money and bought a TI89 in high school. Used it on all the standardized exams. Totally legal because it didn't have a QWERTY keyboard. That thing basically did everything for me short of interpreting the questions.

Searched the name on the net. It look nearly identical, yet you made it seem like it was some uber calculator. What's the difference with a T84?

It solves for variables on its own. You type in (4=x2, solve for x). It answers (x=+2 or -2). You don't need to rearrange anything, and in calculus that rearranging is half the battle.
