3. Tumi Brooks Slim Brief
I buy many more computer bags than I can ever use, but I’m always searching for that perfect one. This is close to that: a lightweight bag that’s perfectly sized for carrying a 13-inch notebook and tablet, with pockets for each. It’s just 11″ x 15″ x 4″ yet has a number of outside pockets for carrying power supplies, cords, a water bottle, cards, pens, keys and other essentials. It has a back zipper pocket to fit over a rollerboard handle and is small enough to pass for a large man-bag as well. ($325, tumi.com).
