Im thinking of buying the booq bp.3 system laptop backpack. I am, however, a bit hesitant. The thing looks like a monster, huge! I do need to carry around textbooks and stuff, but Im not a huge fan of overly large backpacks. I was looking for a messenger bag, but couldent find one that would hold my school stuff: 2 binders, 2 books, and maybe some other crap. I know its alot, and I can shrink the amount of stuff by combining binders. The thing making me lean toward the bp.3 is that it says it can hold up to 6 inches of books + a laptop. Does anyone have this backpack, or know someone who does? If not, does anyone have a suggestion of another case that might work?
