With my new MCB 15" on it's way I want to order a sleeve. I already ordered a Messenger Jackson bag from Fossil but I need some more protection when dragging it from college to college. I searched a ton already and find many mixed reviews about the Incase Neoprene sleeves. In the Apple store USA there are over 90 reviews with an average over 4**** rating. Almost everyone likes the material and the inside, but many people are talking about the zipper. Some say the zipper scratches your MCB others say it doesn't when you when you seal it properly and put the foam on the permiter or something like that. Now I found out that there has just been released the same sleeve wich been redesigned with a new material set and upgraded safeguards. This update is supposed to fix this scratches. The name is the same with a "Plus" behind it. The article is from the incase site: http://goincase.com/blog/2010/03/09/new-and-upgraded-neoprene-sleeve-plus/ The thing that got me wondering is why there are so many mixed reviews. Did the people with the Plus version not noticed that there are two version out there and just put there reviews on the page of the normale Incase Sleeve? They both look the same and I'm sure many people just see Incase sleeve (almost same price) and just post there review there. Though on the Plus version there are only 2 reviews in the store, wich are good but still someone mentioned that you have to be careful with the zippers. Since I don't like the scratches I am wondering should I just go for the Plus version or just buy a sleeve without zippers? I also had my eyes on the Boog Vyper M3, but I am afraid it's gonna be to thick to fit in the Messenger bag. It can fit in the other area where my books go, but propably not in the laptop area. I don't want my macbook to shake between my books and other stuff. With this topic I am hoping people with more experience about this sleeve can give me some feedback and advice me about these and other sleeves that you would recommend. Appreciated and hopefully there aren't to many grammitical mistakes.
