With these multipockets, you can put your computer 17.3 ", but beware, it is not done for every pc, I have an Asus N73S and I have to force a little to make it fit. Otherwise, I can Also put my cell phone in one of the small pockets and lots of other small trucs.Il is very comfortable in the shoulder straps, which distributes the weight well, so no bad back, I tried with the computer , telephone, all the cables that come with it, and my camera. The bag is very durable so you can put many things in it, so it's the best but if I find a little a little expensive, but if was the qualitéau end, it is not looking.
