Wonderfully constructed little backpack.  The sling makes flipping it around and accessing really quick, convenient, and easy!  it's. Also a comfortable and more "modern" way to carry a backpack, the padding on the rear of the pouch saves your back and your laptop.  I use for my iPad, sketchbook, and a crapload of accessories.  The flap extends upwards, to fully xtend and fit a longer laptop, something rigid you don't want to fold etc...
One thing that would make this perfect would be more external pockets.  There's a small zipper pocket on the outside, but I'd like one the whole length, and maybe a water bottle pocket on the side.  Even without, this bag is great for the money. And a good daily commuter bag for men women and students.  Enough room for a computer iPad ebook and accessories.
