Built Cargo Laptop Sleeve

With plenty of people using laptop sleeves as their main computer carrier, one wonders why they never seem able to carry anything besides a laptop. Built Cargo Laptop Sleeves ($37-$47) offer neoprene construction and three external slip pockets, letting you carry a mouse, portable drive, or whatever you need along with your laptop. A great solution for those of you who use a sleeve with a messenger pouch instead of a "real" laptop bag.
