Turntable PC: Coming Soon?

Protein Feed has an intriguing bit about a Fujitsu prototype mobile PC that has a touch-sensitive “turntable” “platter” on the lid so you can scratch videos, ya know, if you’re a nightclub DJ or in a hip-hop posse, or like to pretend you are. It could be on the market in a couple of years. Um, is there a big market for this sorta thing that I’m not aware of?
