[quote name='mywhitenoise']And the people who own one of these, but not one of the other older designs, say this design is good...so they must be right?[/QUOTE]
Having owned all 3 designs myself, my only real problem with the super slim is that the sliding door on top can vibrate a bit and make extra noise. If you put some weight on it the noise is suppressed, but that's not a good solution.
Of course, unless you are playing a game/watching a movie with the system by your ear, you probably wouldn't notice anyway.
