Hi all I currently have a macbook bag which accomidated my previous 13" macbook (Late 2008) unibody. But it fits ok *tight* with my new 15" i7 Macbook Pro. Now, I'm in the maket for protection. Since I have read a few posts on this, and different views, what are peple prefferred thoughts? A incase hard cover style that permantly fits round your mac ? or the incase sleeve? Whichever one i choose, I'll be still using the 13" bag, in addition, as i have all my papers, network cable, Airport express eyc. in there.
