The PSP seems to be increasingly popular because of the fact that it'd a multimedia gadget rather than the fact that it plays games. I mean, I'd probably get one just because I lack an Ipod. If you're a big gamer then yeah go for DS, it has a variety of fun addictive games, and the innovative touch feature. Though the PSP beats the DS out in every technical feature, except for the price and battery power. I'd say choose the PSP, but it's really your choice. I've played the DS and it's extremely fun.
