Ya it may be a little too big, but this is a modder not a Nintendo engineer. Give him the right resources and I bet he could really come up with a small handheld with truly amazing power. Heck, the Gamecube came out sooooo long ago. We should have the technology by now to greatly increase that power and decrease the size.
Just waiting on Nintendo and/or Sony... COME ON YOU GUYS THIS IS AWESOME!! Give me a superior handheld that I can truly enjoy and I will be glad to jump on the bandwagon.
