Call me crazy, but the best thing about handheld game consoles like the Nintendo DS and the Sony PSP is that they're portable. The graphics aren't as great because they had to cram all the hardware into such small packages, but hey, you can bring them with you on road trips.
This gigantic Nintendo DS/Sony PSP arcade cabinet, then, really confuses me. I mean, it's neat that someone was able to run those handhelds into this machine, but why? Why not a full console like an Xbox 360 or PS3? I guess the world will never know.
