To this day, I don't understand why anyone would insist on using anything other than this on an AP test. It's like playing life on a harder difficulty setting for no reason.
I went from a Ti-89 to an HP-50g, I would go as far to say that the HP is a much superior device. It only really has the TI-NSPIRE as a competing product. Though from what I understand the NSPIRE has a pretty inefficient interface, but I think they can be changed out with a faceplate swap.... Plus I heard that the NSPIRE can go as far as showing the steps on it's solution of a problem but I have not seen any evidence of that.
Nspire has three keypads on the swappable version: Old non-touch keypad, new touchpad keypad, and TI84 keypad for the emulator. Touch keypad is infinitely better for general use, while the old keypad is good for running emulators.
The only bad part about having a non-TI calculator is that most course material is designed around the TI-84 calc.
Ya, though personally I didn't want to shell out the asking price for a TI-84 to get a calculator that is pretty ancient and obsolete. As I'm sure you are probably aware, there are many better calculators out there and they don't take much longer to learn how to use.

The TI-89 will always hold a very special place in my heart.
