Unless you've got a penchant for going the ultralight route, chances are you've got a DVD or other optical drive in your laptop that you rarely, if ever, actually stick a disk in it. This concept, dubbed disk+Mouse plans to put that space to good use holding a pointer that stores flat, but pops up in a conical shape when needed. Of course, by this time next year we'll all probably be looking at physical media the same way we did floppies in the post iMac world and this will be nothing but a cutesy throwback with no place to go -- just like those cassette-shaped USB drives.
