PlayStation Move. The site performed a teardown on the new controller, examining how easily it could be repaired should one of your friends decide to throw it, full force, at the razor-sharp corner of your living room coffee table. (Don't they know that motion controller-related accidents are so 2006?)
You can check out all of the controller's inside-parts over in IFixIt's teardown -- unfortunately, though, they didn't crack open the orb which tops the device. We think it has something to do with them not wanting to injure the magical, polychromatic fairy which lives inside of said orb.
