Ordered the 15.6" in brown, and liked it so much that I immediately picked up the black one, too. Has the look of a much more expensive business brief/case. The shoulder strap, handles, and all metal connectors and clasps function very nicely, as does the strap across the back to attach to your upright suitcase handle when extended.
Easily holds my 13" MacBook Air (would certainly accommodate a laptop of a much larger size) along with my iPad, padfolio, and any paperwork files, as well as a book if I am traveling. Pens, highlighters, etc. as well.
Perhaps the best part? When I ask a person to guess what I paid for it, they always guess well north of $150. They are shocked when I share that I paid less than 1/3 of that. Very highly recommended!
