Concept Idea: Next Gen Videogame System

I was thinking that the most frustrating thing about consoles is that it sucks to carry them around and connect them to other tvs. I like the ipad/ipod touch because, as gaming devices, having a system that is - it's own screen - is wonderful. Maybe the next generation of consoles should be like an ipad - have a screen for viewing and playing, but also have an HDMI port to connect to larger tvs for improved sound and graphics.
