i've got a DS and i've had it for months i got it at Christmas and i've had no problems at all with it so far, the 2 games i've got for it are both great and i've enjoyed playing it. In my opinion i prefer it to a PSP because the PSP games confirmed so far seem to consist mainly of ports of PS2 games, and i have a PS2 so if i wanted to play those games i could use my PS2 and not have to pay $250 for a new console.
So does the DS
