Back when I used VPC, I used it for...not much really. I tried playing a game called Castles of Adventure on it, but the sound was horrible and the game was so jumpy as to be almost unplayable. I also did TI-89 assembly development on it, using the Virtual TI emulator to test my programs. VTI is actually usable on VPC - it's one of the few programs I've found that runs at an acceptable speed.
