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!"

Get the TI-89 Titanium mug.A device that qualifies colleges for free stuff: By stating that students are required to purchase the TI-89 Titanium on their syllabi, colleges are qualified for free equipment and emulator software from Texas Instruments. (from department minutes)
This device is so remarkable that some students can ace a math class with it, but without it cannot add 1/2 + 1/3.

Dean's secretary: Hey, you didn't put on your syllabus that you require the TI-89 Titanium.
(Dean walks in.)
Instructor: That's right. Doesn't it seem unethical to require students to pay $150 or more for a calculator so the college gets free stuff?
Dean: No, not at all.

Get the ti89 mug.The Holy Grail of Calculators. This baby can do everything from calculate how much you need to tip your lovely waitress to graph a complicated integral that even your Calculus teacher will be amazed by. O and don't worry it can do much, much more. Too much, that a normal human could never actually figure out all it's features in an entire lifetime. It is the Ultimate / Only friend of an Engineering Major.
Kim : I looked up Calculator in the dictionary the other day, and it wasn't defined!
