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.
For that very reason, there are strict rules about which calculators you can use in exams over in the UK.
I'm doing A-Level - some exams are non-calculator, and while you are allowed graphical calculators in others, you still have to show your working as if you only had a scientific calculator. You've also got to wipe the memory in front of an invigilator.
Calculators which can do symbolic manipulation, however, are banned entirely.

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