I noticed that the lid on my new MBP 15.4, when closed, isn't completely flush across the entire casing. You can push down one side of the lid and the other side pops up higher centering on the latches, basically being able to rock it back and forth a little. Could the aluminum be warped back a little, making the top part not close flush to the bottom part? I went to an apple store and looked at about five other 15.4s and they all had this similar issue, some more than others. The two 17s I looks at didn't have this issue, they were completely flush across the entire casing. My old 12 PB G4 didn't have this issue either. Anyone else notice this? I would say that mine is "within spec" if the other 15.4s had this as well (probably what the genius would say as well). Besides this small annoyance, everything else is perfect. No wire buzzing sound and no yellow screen, so I am not sure I want to risk taking it back and getting another one.
