i just asked my younger brother today what he might want for xmas, and he was telling me that his 15" pre-unibody macbook pro gets really cold on his drives to and from school (30 minute trip). he said he has a cheap case for it but whenever he gets his mbp out after his drive it won't turn on for a while until it warms up. he was wondering if i could find some kind of insulated sleeve for his 15". is that the solution? any recommendations on what brand to get? thanks in advance!
