So I just bought a MBPr, I understand that the aluminum body is supposed to act like a heat sink for the macbook. But when I go to use my macbook in the morning it's utterly too cold to even place on my lap without getting frost bite. What can I do? Does anyone have any methods for keeping it warmer that work? I was thinking about keeping it under the covers? Or putting it in a sweatshirt. But then I was scared of being one of those people who treat there dogs like humans and dress them up... except instead with a MBPr. P.S: I haven't install Flash with this new MBP, so I can't heat up my laptop using it.
