Wally: The biggest tech companies want to win the battle for your living room. But they are unwisely focusing on developing better TV sets. Today I give you me design for a fully digital couch. It has all of the features you would expect, including a butt warmer, surround sound, bottle opener and back scratcher. But you can also control the lights, curtains, temperature and TV by using your buttocks like a mouse on the seat cushion. This is a loft click and... this is a right. The prototype arrives tomorrow, and I'll be testing it for the next six months. Maybe I'll sell my house.
