I have always liked the idea of carrying games around. I owned several handheld gaming devices and wished for console quality. Tablets approach this, but I have always been disappointed. I don’t think tablet gaming can or will take off until we get physical controls baked into the tablets. The XPeria play did this with a phone, and I think something similar might be done for tablets.
Without this I think tablet gaming is going to be stuck in the casual realm.
