I already have a Swiss Army notebook bag that im very happy with. Now I think im going to get a 13" macbook pro. Can I use the 17" bag on the 13" Pro? Or will it just slide around to much?
If you have access to some fairly thick Styrofoam (anything flimsy will get crushed by the laptop), you can cut a piece around 4" wide that can fill the gap between your laptop and bag.
