Ok, so with the new MBP very likely coming out in just a few short hours and the forums full of people, I figure this is a good time to ask. I'm heading off to college next year and need a good, sturdy backpack or similar case to carry my soon-to-be-purchased MBP. I'm looking for something that'll keep the computer out of harms way, but still has enough room to carry books and such so I'm not carrying tons of bags around campus. Any type of bag or case will do as long as it has plenty of room for storage. Any recommendations?
