TI-89 Titanium

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!"

TI-89 titanium

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.
