Hey, all. I just got a new 15" Unibody, and I was looking for a good hard sleeve. I had the Vyper M2 for my old MBP, but I hear the new Vyper M3 for the Unibody is not a formfitting as that one. I was just wondering if anyone out there has it, and if they can tell me if that's true, or is it just as secure (not too much, if any, give) as the Vyper M2. Thanks in advance.
