I have been trying to figure out what case to buy for my MacBook. At first I had my eyes set on the STM Small Alley bag, but after seeing it in person I realized it wouldn't be ideal for grad school as I will have to carry some books every now and then. I also realized that I allready have a rather nice black leather messenger bag that is more than big enough to carry both my laptop and books when needed. Only problem is that it offers no protection for the computer. I have been coveting a nice neoprene sleeve for my computer; I like the Incase one but it never seems to be in stock and people have been complaining about its lack of zipper protection. If anyone actually has the MacBook Incase sleeve (the one specififically designed for 13.3" computer), could they please post a mini review.
