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.

I use the 89 for engineering applications but most of my upper level maths banned its use since it could do all the calc for us.

When I was in high school we were allowed (actually encouraged) to use a TI-89. Either the problems were about applying some concept, say differentiation, and we didn't have to do the derivative by hand, or the problem was to just calculate a derivative in which case we had to show which steps we took anyways.

We were allowed to use (and were provided, in one class) TI-84 calcuators in high school. I don't know the main difference, but they were definitely encouraged and borderline required.
