Just got a MBA 11" and so far I love it. I have a couple of questions I was hoping someone could help me with. 1) Does anyone notice that when you first start up the computer, you can hear the fan spin up? I can't hear it running under normal use, only when I first start it up. Just want to make sure it's normal and not a loose fan or something. 2) Keyboard protectors. I picked up a Speck SeeThru case and love it. Only problem is when used in conjunction with an iSkin keyboard protector, the computer doesn't close all of the way. I ordered a Moshi one, since it stated it was thinner, but didn't know if it would be enough.
