I've got a PB G4 12" that's about a month old. Just today, I noticed that a bit of the casing on the right side seems to be loose. It's the part of the casing just to the right of the latch release button, between the battery and the palmrest. (This is the piece that's like a strip of aluminum that goes all the way around the computer, making up the vertical component of the case.) Between the right corner of the computer and the latch, it seems to be a little loose, bowing outward just a tiny bit. It also looks like there maybe a tiny bit of play between that bit and the edge of the horizontal palmrest. I mostly notice because it seems somewhat assymmetrical with the left hand (non-battery compartment) side. So, is this something I should worry about? Is it normal? Is it worth trekking into my Apple Store for? Should I expect anything of Apple? Thanks in advance.
