I received my MacBook Air about a week ago and I am very happy with it. I no longer carry my old MacBook Pro. Instead, I carry my new MBA and iPod Touch. I am waiting for my portable hard disk that will go with it. 64GB just isn’t big enough.
It is incredibly light. Keyboard is just perfect. The only thing is that when it gets hot, it makes pretty bad fan noise. I thought if I get one with a solid state hard disk, there wouldn’t be any moving parts. Apparently, there is one. I wonder if one can design noiseless fan.
