Expanding on Passenger88's thread, I need a laptop backpack for college. I'm almost sure I'd rather have a backpack than a bag, but I guess a bag could work if it would provide a lot more protection. For the backpack I was thinking I'd also buy some kind of sleeve to provide further protection, but there may be some backpacks that already provide a good amount of it (doesn't allow for scratches). Anyways at the moment I'm assuming $200 is the budget I'd like to stay in (just because I'm dropping 2.5k on a new MBP). Also the MBP is a 15". Edit: Should be able to hold my school stuff too, no point in having 2 backpacks.
