A high-performance calculator made by Texas Instruments. With a computer algebra system, it can evaluate algebraic expressions symbolically, rather than just giving a number answer; and is therefore much more powerful and difficult to use than the TI-84, the common graphing calculator used by high school and college students alike.
"Hey, Jack, where's your TI-84?"
"OH, I left it in the trash can. Check out this great TI-89 Titanium I just got! I won't even have to know how to do math anymore!"
