It is interesting to note College Board's policy on the AP Calculus exam: the TI-89 is permitted, but not the TI-92. For them, exam question security is a large issue, and machines with a QWERTY keyboard permit fairly easy transcription of test items.
Some tests are starting to disallow the TI89, too, because of its symbolic manipulation capabilities.
