I want one!    
(fits up to 15.4" notebook measured diagonally)   
picenum
Notebook? What notebook? This shoulder sling bag is a pleasure to carry. picenum’s one-piece design has a large dedicated snap closure pocket for your (up to 15.4”) notebook and a giant inner cavity suitable for carrying a big 17" notebook and everything else you’ll need. The integrated strap distributes the weight of the bag’s contents over the arc of your shoulder. The shock from the cargo weight is absorbed by the slight stretch of the neoprene as you walk — letting you become 'one' with your notebook. If you think at all about the bag, you’ll think: This is awesome. See the wide palette of distinctive colors on the “I want one” page. Price: $59.95.
