OK, add me to the list of 'creakers' (creakees?). When you pick the 13" MBA up by any one of the corners, sure enough, it creaks disconcertingly. So, if this were a $499 Acer I wouldn't complain, but this is a $1,800 4GB/256GB Apple, so I am complaining! I took it into the Apple Store on 14th Street in New York and they looked at me like I was some sort of alien when I asked them to take it in the back and crank down the screws to make the creaking go away...then they brought it back and said the screws were as tight as they were supposed to be and they wouldn't tighten it any more...creak, creak, creak...
This is a real issue, not someone's imagination. Apple, when will you fix this (please!)?
