I just got my 2.66 yesterday and so far I love it. However there is one thing I noticed right away... the enter key makes a crunching noise when I push it in. The left side of the enter key seems to be grinding in the aluminum cut out. It still functions but it is driving me nuts! I have also noticed that the right side of the space bar is noticeably higher and stiffer than the left side. What should I do? Call in to Apple or an Apple store? Will Apple replace the whole keyboard and upper aluminum panel together?
