I have a 15" Macbook Unibody and have been looking for a good case for quite a while, I purchased a Crumpler Gimp sleeve a while back but the fitting is really bad, its too tight and the zippers hit the corners when I try to close it, so I no longer use it, and yes its definitely the right size . From what I've heard, Incase sleeves are the best but I'm not sure which one to get. Here are my options: http://store.apple.com/uk/product/H0375ZM/A?fnode=MTY1NDA2Ng&mco=MTc1MTc3NTg&s=topSellers http://store.apple.com/uk/product/TX677ZM/A?fnode=MTY1NDA2Ng&mco=MTc2NDg5MzA&s=topSellers One is canvas and the other is neoprene, I was initially going to go with the Canvas one since the material is thicker so I thought the protection would be better, but it'd be nice to hear from anyone that knows anything about either case. Also, the review on the canvas page says the fit is very tight so I don't want to have that problem again. Thanks for any help!
