So I got my macbook a couple of weeks ago, and I've noticed a couple of things regarding the case. On the lower body in the left hand side where the cosmetic screws are, I can push in on the case. It gives in about a centimeter, but there doesn't seem to be any visible exposure into the body of the machine. Secondly, the battery does not sit flush to the rest of the case (the battery is actually narrower than the case). Should I be concerned? I took it in to the store and showed the geniuses, and they believe there's no concern about either issue, but they did make notes and provided me with case numbers. Should I take what they said at face value or should I be a little more proactive and be concerned about this?
