Hulk makes an excellent point. Also we've had Nintendo for portables for a while, thus we know their games, and getting venders for them isn't too hard. You say PSP has better hardware, but the DS goes beyond just simple hardware. Its potential beats just a simple handheld...
Its more than that....
As a FanBoy response...
Fuck the PSP up its ass... The DS shall own you!...
Yeah both sounds good to me, but I'm getting the DS first.
