This bag is perfect. I can fit my 17" widescreen Dell Laptop in the bag perfectly. The great thing is I can load it up with a ton of other crap at the same time. If I have nothing in it, I can sinch the sides with the straps to fit my size needs. There are a ton of compartments to keep things separated. The seller for me was the rainguard. I ride my bike everyday with this backpack and getting caught in the rain would have been a real bummer, especially with my laptop. Not with the rainguard. The yellow color might put off some people, but I like the visibility!
