Hey all. I am going to be picking up my very first MacBook Pro with retina tomorrow. I invested in a very nice Samsonite bag for transportation, no my concern is a case. I see a lot of people with the Speck cases; however, I have heard that any type of these shell casings can cause the MacBook to overheat? I was also told this by a geek squad rep as well. What is your opinions on this matter. I just have a hard time spending $1500 on a laptop and not offering it some protection; however, I certainly don't want anything to overheat. Thanks all, and have a great weekend!- Ricky
