A robot! I know it sounds a little ridiculous and far fetched but that's the kind of innovation that could be a game changer. I think this is something Steve Jobs would do - give the public something they aren't even thinking about. I'm not talking a toy either and it would be expensive (probably in the $5,000 range) I'm talking about something utilitarian but could end up being a part of the family - do chores, have conversations, play games, etc. Imagine all of Apple's resources and knowhow and what they could do. And if you think the technology isn't there, look at what Honda has been working on for 20+ years.
