A device created by Texas Instruments primarily as a productivity sink for math students. Has long since been replaced by models capable of creating even more distraction (like the TI-84 Plus).
It is true that I would never have gotten through college calculus without my TI-83, but seriously -- what did my professor think I was doing with it out in the middle of friggin' July with all the other summer school tards?

An inferior Graphing calculator. The Casio 9850 is far superior.
I laugh when my friends drop their TI and the cheap ass battery cover breaks and the batts fall out and all their games are lost.
