Ok, I know similiar topics crop up all the time, but I've searched the forums and haven't found much information that applies for my situation. I'm heading off to college this Fall (majoring in Political Science) and need a case for my 15" MBP. My decision is between getting a Brain Cell (or Monolith) and a Brain Bag, or getting a School Hymn and getting a different backpack. My primary concerns revolve around how much protection either of those cases offer (I'm lumping the Brain Cell and Monolith together since they're basically the same). Another big concern is how much the backpack will hold in addition to my MBP, as I would need to carry several textbooks and a notebook. Any advice is greatly appreciated.
