Hi all, Picked up a space grey 1.1 model today. Really enjoying the form factor; now I have to sell my old MBA. I was wondering if anyone has had any issues with the Macbook creaking? When I pick it up or adjust the hinge I sometimes hear a creaking or clicking noise. I'm not positive but I believe it might be coming from the bottom of the case where it is screwed in. Anyone else have these issues? Or anyone know if this issue could be fixed by tightening the screws on the bottom case? Thanks for the help.
