I bought a 13" Macbook Air yesterday. I had a 2009 MBP before and have been waiting on the refresh to get this. The machine is great. Quick, responsive, light, But one thing Ive noticed is that when handling the machine it makes creaking noises. Sounds like the body is flexing. I took it into the genius bar and the guy took it in the back, said he heard it and then said that it is normal even for the previous gen because of the thin body design. SOOO, my question is , does anyone elses 2010 MBA do this as well? P.S. I tried the display in the store but it is too loud in there to hear it.
