Im a DS girl myself. There's something about being to take my game with me to the outhouse that I enjoy a little too much sometimes. Wierd though, I couldnt get into the PSP at all. Darn Sony.
I am all for PSP. (-Good graphics, wide range of games, ability to screen movies <-But the subtitle gets loose a little bit, the negative side of PSP) I think it's up to 8 Gigabyte, able to store about two '2-hour movies) and 2 Games.
My sidekick is for X-Box and PS3. Graphics and the range of games are comparable. Nextly, we can go live on it.
