I know there are a lot of threads on this but I'm looking for something for traveling, not daily use. I want something with a padded compartment for my macbook (I don't have a sleeve) AND enough room for a couple days worth of clothes and stuff. I have a school backpack but it's not big enough so something bigger than your standard school backpack... Also, I would like to keep it under $100 but could be swayed up to $150 if it really met my needs. Thanks!
