Hello, I have owned my new MB for about a month, and just last night I noticed that when the lid is closed, it is misaligned with the bottom half by about a half a millimeter. I noticed it because I could feel the edge of the lid ever so slightly hanging over the bottom up be the front right corner. I realize this is a totally cosmetic thing, but it is really bothering me. Is this within the standard variability of the product, or is this something that I should be concerned about? Does everyone else's MacBook lid line up perfectly?
