Mostly Harmless

I was gonna write something pretty much exactly like this, someday: SideTrack

A scrolling area on your trackpad is exactly the sort of thing you need when web surfing while lying on the couch with your laptop computer propped up at an odd angle.

A 42″ plasma computer display mounted on the ceiling — with a cordless scroll mouse and keyboard — would probably be a good solution too. Bit pricey though.
