I own a 13" Macbook (Early 2009 model), loving it! But I need a backpack for the college with the regular space for a 13" Macbook and some space for my notebook, maybe a regular book too. I was looking for the Alienware Orion Backpack, which I really find cool, but I think it's gonna be too big. Any suggestions? I need a REALLY good quality backpack plz.
