Aw, PC, don't get that look on your face. You're not fat, you're just well-built. Just because the MacBook Air is incredibly thin and sexy doesn't mean I love you any less. I mean, you've got so much more personality! You've got things like a built-in ethernet, optical drive, removeable battery AND user-upgradeable RAM and hard drive. That slinky little b*#*% doesn't have any of that.
