Apart from mucking around with the aesthetic there isn't a lot you can do. Angled keyboards and strange mice never did for most people and what we have now works pretty well. Devices like Kinect are wholly impractical for the average user and most people don't want to stand around using their entire body as a controller when 2 hands will do. so yeah, I'm really curious as to what they think is being overlooked.
