Boa Flow M I am in need of a backpack for graduate school. I really want to buy something solid so it will last me for a few years. I currently have a 15 inch MBP, and I will be needing to carry some thick legal text books with me. Anyone have experience with this bag? It looks great, but I know I dont need the camera pouch and I'm not sure that its designed to fit larger books. At the same time I really want to avoid something very bulky. Any suggestions or advice would be greatly appreciated.
