Hey all. I'm looking for a hardshell type case for my 17" MBP I currently have a booq vyper sleeve and booq backpack. I find that the MBP will want to slip out of sleeve if not tightly zipped up. It has done this twice now, and I have minor dents on my corners. Anywho, I think I would rather just have it in a hardshell case all the time, and not worry about dinging it. I looked online at the InCase and Speck models. Any input for purchase would be greatly appreciated.
