I fly weekly for work and limit myself to a carry-on and a personal item. All of my personal effects go into my carry-on, and this bag works great for everything else. It's amazing how much fits in here: 15" laptop, charger, iPad, misc. cords, documents, books, earphones, sunglasses, wireless mouse, and all of my office accessories. One of the great features about this bag is the open zipper pocket on the back that allows me to slide it onto the handle of my carry-on for easy traveling. The bag unfortunately was stolen a few days ago, but I love it so much I am ordering another.
