whoaCouldn't just people use the screen on the dock?
What if the NX dock was made to be held? It could be a flat, rectangular box made to snap back-to-back with the NX screen. Or a boxier shape, like a jumbo N64 rumble pack. And then it streamed the video to a dongle on your TV. It sounds practical enough, the only major issues are the power cord needing to be connected to the dock, and the whole package being too heavy for comfortable use.
Regardless, it's a cool idea. I never thought about it before, and I've followed this thread pretty damn heavily and considered pretty much every possibility, lol.
