Hi all, Bought a Macbook Air a few months back to replace my aging MBP. Love everything about it so far, but one small concern. Whenever I pick up the MBA, It almost feels like the bottom of the computer, the casing, is slightly loose, it feels like something moves when I put my hand under it and lift. I know this sounds crazy, but just wondering if anyone experiences a similar thing, or if I should take it in to get looked at and possibly tightened if necessary.. Thanks!
