Some of my favorite everyday use laptop bags
  1. Topo Designs - Mountain Briefcase
    I like the simple design of what looks like a simple briefcase style bag. What I like the most, however, is its well hidden bag pack straps so it can be carried in three ways: backpack, shoulder strap, or handles. I wish there was more organization inside the big outside pocket instead of just completely open, but the overall functionality out does any short comings.
  2. Timbuk2 - Command (tsa friendly)
    This one is a classic messenger with the added benefit of being able to unzip the laptop section for easy TSA screening at the airport--without removing your laptop from the bag.
  3. Evernote - Triangle messenger
    This bag's ability to standup all the time makes it rad. There's plenty of space for things like big headphones, but the bag is still compact and manageable.
  4. Alpine Division - Marshall
    Slim and minimal laptop bag with plenty of organization inside. Works best with a 13"-15" laptop.
