PSP
A fairly expensive portable system. Can display near PS2 quality graphics, and also can play movies and store MP3s.
Basically, if you have the money to spend and want more than a game system, buy a PSP. If you have a smaller budget and want a game system, buy a Nintendo DS. Oh yeah, the PSP has less battery life than the DS. Also, Sony has such a fanbase that most people won't consider buying a DS, though it is (IMO) the better system. Damn Sony fanboys.
