The last time I bought a laptop bag was about 15 years ago, so needless to say, the improvements are astounding! Two big concerns: first is functionality. I was always cramming in the IPAQ, Digital camera, laptop stand, power supply, cordless mouse, and other little digital necessities. I worried about if they were pressing too hard on the top of the laptop and I had to be careful nothing fell out of the pockets. For starters, this bag has all sorts of secured little pockets to hold all this gear while protecting the laptop in it's own padded compartment. Second concern is security. The Exomesh exterior, non slip shoulder strap and combination security lock is more than I expected at this price. Every time I use it, I'm amazed at the quality and functionality. Oh yes, and everything fits nicely with room to spare. And there's an outside pocket for your bottle of water too!
