I'm really super excited about the Gameboy DS because it's new and innovative, and could totally change the handheld market (Again) but, on the other hand I really don't care very much about the PSP. It's pretty bland, and there's not really any original games for it. But, that is of course my humble opinion. Really though, I would like to know what other people think. Are you going for the DS, or the PSP?
