Camera Backpack

With my new camera gear I’m scoping out, I am wanting to get a bag that I can store it in as well as use as my primary travel bag when flying. I tend to leave the camera behind for my yearly treks to Macworld and WWDC due to the space constraints of my messenger bag, so I am looking for a backpack that can hold the following:

  1. MacBook Pro 15” + power adapter
  2. Small USB drive
  3. SLR body
  4. 2 lenses (most likely in the 50mm and 17-135mm range)
  5. Extra pockets for small accessories (Field Notes, pens, magazines, etc).
  6. Fits under an airplane seat (not essential but would be nice).

If you have any suggestions, let me know.
