I would say the DS, even though the new one seems to be very much designed for younger kids. I have the first DS and personally think it's the best of the three.
PSP is nice though. It has a lot more features and is more adult like. I just don't like the design as well and a few other things.
lol DS sucks... PSP is amazing, not to mention that all the games for the PSP have an actually good story line, and are quite long... You can also dl games and demos from the ps store.. So yea PSP is 100x btr than DS.. The games for the DS are to childish and kiddish for me.... well other than brain age which is a game that just pisses me off haha

Yeahhhh....
Also DS can play gba games which gives it an even better library than the psp. DS literally has more games than the psp by a wide margin, this was simply a list of my preferences, and to also show DS is not simply for children.
