I just picked up one of these RMBP and I wanted to see if you guys had recommendations for cases. I play to carry it around in my backpack but would like an extra layer of protection for it. Will cases for the last generation 15inch inch MBP work for the new RMBP? I see that the incase is pretty popular and was looking for something along those lines...something that has cushion, tight fit and will fit into another carrying bag. I really appreciate your guys' input!
