I bought a Booq Vyper M2 sleeve for my new MacBook Pro after reading a lot of positive reviews, but I am a little disappointed. It definately does not fit as snug as I had anticipated. The width and depth are fine, but it seems to have too much room on the height. For example, I was able to put 4 magazines (MacWorlds) on top of my MBP and still zipper up the Vyper quite easily. If you have or used the Vyper, is this how the fit is? If so, do you find that it slides around much, or is it okay? Thanks for your help.
