Hi all, Well, after issues with the display panel in a 13" MacBook Pro (that led me to return the MacBook Pro about a month ago), I decided to get one of the new MacBooks, considering its specs were fairly close to the base-level 13" Pro model. I picked it up today and, when setting it up, noticed that it doesn't sit level and noticeably rocks back and forth from the back left corner to the front right corner. When my hands aren't on the computer, it rests back towards the left corner, but the second I put my hands on the palm rest and keyboard, it rocks forward with a small "thud", as the front right corner hits the desk. It's significant enough to be uncomfortable (not every laptop casing, "feet", etc. is perfect, but the amount of movement here seems excessive). I placed the MacBook on other tables, counters, desks, etc., and it still does this, though the degree to which it does varies a bit. Also, I took a screwdriver and checked all the screws to make sure they were firmly in place (so that no section of the bottom case was loose or sticking up). And, at least to my eyes, I don't see any noticeable bulge or unevenness in the bottom case. I'm curious -- any new MacBook owners have a similar issue? Any thoughts?
