Like the idea of a few things.

Like the idea of streaming your games on friends consoles and if you are stuck on a game they can take control on your console and get you past the bit your stuck on.

Also the hard pause so you can switch off the console then when you switch it back on it will be exactly where you left it.

Also Gaikai features will be great. Every game on the store and trials playable immediately before purchase.

Had to laugh at the complete rip off of kinect and the Wii U's streaming features though and how quickly they just glossed over them.
