We purchased this backpack for our new 17" HP laptop. The website was very good at helping us pick a backpack this laptop would actually fit itside. It also has the special pocket that, hopefully, will make getting through airport security checks easier (don't know yet - I fly with it for the first time tomorrow). Very heavy duty contruction and well made zippers and pockets. My only complaint is that it is so big, my husband can load so much stuff in it that it winds up being pretty heavy. No slinging it over one shoulder for long - you need to use both straps for the load! EDIT - made it through the airline security perfectly - did not have to remove the computer, just opened the special zippered compartment! They did find my water bottle though - I had forgotten it in that deep side pocket! I met someone else in line with this same backpack. He had been using it for 2 years and it still looked great.
