Don't know about the MacBook Pro but the G4 iBooks are definitely sturdy. Mine was yanked out of the bed a couple of times, was dropped off a table a couple of time (damn those cables!), fell out of my backpack on an escalator and once went flying down a flight of stairs on a tiled floor. Still works with only minor scratches. Well, the hard disk is making funny noises. I probably should backup more often.
