PSP can do everything :o
Mine has the camera, is hacked, can play anything from PS1 trough sega and nintendo to DOS games. Has the nice games, good graphics, ... I can't judge the DS since I never had one but from what I see everywhere, it isn't lovable. But I do have Nintendo's Donkey Kong (It's dual screen, from 1982). And I like it a hell lot, and it's like having an oooold DS. And I prefer that DS. About the movie, I like it alot. There could have been a splatter sound when the nerd screamed though, just for flavor.
