I'm hunting for a new school bag that will work well with a MB and I'd love some advice. I'd like a messenger-style bag and I really like the vertical orientation like on the Crumpler Luncheon bag. Also, it needs to be big enough to hold some books in addition to a laptop (so a Medium Alley from STM is too small). I guess I'd just like to hear different people's opinions on laptop bags and any other suggestions. Thanks!
