I'm awaiting a MBP in the next couple of weeks, and right now all I use is a Jansport regular ole backpack and a sleeve. I feel like it's time to get a laptop backpack, especially since it's a 15". Anyone have any suggestions? I usually only have a notebook, but I'd like room for a small textbook in addition to the notebook (paper and electronic ) and obviously pens/pencils. Most backpacks just seem too big and my back can't handle more than one textbook and a laptop, so there's no reason to have a huge pack made for 2-3 textbooks on top of the computer.
