That's basically what the 3DS is. Tons of awesome games on there.
... and a gimmick which just drives cost up and my interest down. GBA was where it was at. All the morons need to do is progressively increase hardware power in handhelds, not hamstring them with stupid gimmicks. When you're already many generations behind console power you should be doing everything you can to get as close to caught up as is possible. I don't need a fucking stylus to play games, I don't need two screens, and why the fuck would I need 3D when I don't even play my console or PC games in 3D?
