So I was looking at some cases, and I was really considering getting the same Neoprene Sleeve that I had for my previous 13" Macbook that worked great, but I read some reviews and heard there was extra slack (loose case), and I don't want my new laptop flopping around in the case. http://store.apple.com/us/product/TR633LL/A?fnode=MTY1NDA2Ng&mco=MTk4Mzc3MA And this would be for the new model macbook pro, I don't know if the sizing is any different or what the bad reviewing users have as laptops. I guess while I'm at it.. is this a good choice for a case? Any other recommendations? My MBP is still shipping, but I really want to have a sturdy case before I actually get the computer. Thanks!!
