I purchased two of these backpacks recently and even my work colleagues have agreed that they are amazing laptop backpacks - they have oodles of space and are the upper end of the Wenger Swissgear range.
They have a laptop section to the backpack, but my work colleague (who is incredibly hard to please) is happy to use it for all of his backpacking needs. I won't go through everything here, and as a picture speaks a thousand words so take a look at the Pictures on Misco, they're pretty comprehensive. The number of pockets in this thing are insane, and very, very useful.
For this price, I'm well and truly chuffed! Oh and the Red colour is incredibly nice too.
