Maximum PC

Got me thinking.

Are their any small track balls and keyboards i could combine with a small monitor. The idea i'm thinking is to have a sort of Mini PC i can plug into my laptop when im on the bus and the full real estate would have me bumping elbows with my neighbor.

Set my laptop to slep the main monitor and have a 7 inch window with attacked track ball and slide out keyboard to watch movies from my hard drive when elbow space is a premium and i can't open the case.
