ALL PS is all in wonder house = play alright/crap games + watch video + listen to mp3 + surf the internet + extra if you get anypsp below 2.0.
Anyways DS is all about games and i love :
ANimal crossing
Mario Kart DS
Advance Wars: dual strike
Mario & Luigi
Zelda: The Minish Cap > GBA
Mario & Luigi: Superstar Saga > GBA
FFIV Advance and crap loads of other GBA
PSP Title i recommend:
Burnout Legend
Luminess
GTA : LIberty city > I didn't like it but if you ARe a gta fan then you will like it
Thats all :!
I own both and I highly recommend DS because its going to get even stronger than PSP and PSP is starting to loose developer support...
If you think Socom + Twisted Metal are great than you really need to play the PSP for few hrs to release they are the greatest game in teh world. PSP needs few good title to really make a break through now. PSP last 3 title that may save or kill the PSP would be : Devil may cry , GT and FF7. But I like the FF on Gameboy. Any RPG fan would buy a DS as it can play old gameboy rog games + DS rpg. PSP still doesn't have one good RPG on the system :!
