i own both and trust me the PSP is RADICAL. it has 10x better graphics and functionality than the ds. The PSP is also been out for about a week and it already has 24 games. the ds only has 6-7 and 3-4 suck(SPRUNG<PING PALS<FEEL THE MAGIC<ZOO KEEPER<POKEMON DASK)these games all Suck big time. 90% of psp's games kick a<<. The $100 extra dollars should not hold u back. the psp also holds memory sticks which add an uncomparable new dimesion of game play. the 2 screens on the ds is a crappy gimmick that nintendo uses to pull in 5 year olds. plus who wants pictochat anyway. why write to a person on an annoying smaal screen 20 feet away when u can talk to them?????????????? GET THE PSP> TRUST ME I HAVE BOTH!!!!!!!!!!!!!!!!!!!
