I had fallen in love with this rucksack from Cote Et Ciel (I even love the term rucksack) last fall, and I got mine two days ago through UPS (probably the only courier that makes us feel less cut off from the rest of the world).
First of all; it's absolutely gorgeous. The gray material which looks like gray jersey (which I also tend to like a lot) is in fact a thicker sturdier fabric consisting of recycled water bottles (!!). To make a long story short: it has a separate part for laptops up to 15" and all the necessary cables, mice, wires, etc. The front "compartment" is very spacious, zips-open vertically. When zipped-closed, it folds and secures on one side. See more images and info here.
