I broke my blue tooth my throwing it across the room against the wall and it exploded on impact. (not chemically, obviously).
and then I've managed to snap one of my sixaxis in half just about. All the plastic screw casings holding it together are broken except for the middle one. Luckily the sixaxis isn't complex as it still works fine I can just pull the front and back plastic away from each other on either handle.
All my game rage is of course caused by the wonderful COD4.
