With three DS types in existence -- we're including the Phat here, too; can't forget about the original just because these upstarts are hanging around -- you have the potential to build one weird system. If, that is, you combined aspects of all three. If you could, which features would you put into your handheld, and which would you discard? Maybe you don't care much for the DSi's camera, and you want a slightly thicker portable. Maybe you want the camera plus the GBA slot. Maybe instead you like one of the versions just as it is. How would your DS look?
