I am too sold on the "remote TV" idea, however, I have to wonder if it's still too early and too expensive tech-wise, and there are a lot of questions to be answered
- Range?
- Battery life?
- More than one controller with a single WiiU?
- Is the Wiipad really absolutely useless without the WiiU? With a 6'' screen it's already the best "portable" bed-time console ever made. If it has DS-like performance by itself I hope to be able to use it.
...

Also: I clearly remember a Meego demo about having the "tablet" content shared to the big TV screen. I wonder if the Wii U will get there first.
