First, some background. I travel on commuter rail over three hours every day, and my bag is essentially my mobile office. So the design and ergonomics of that bag are critical. Also, I'm frequently required to attend various meetings all over NYC, and I end up hauling this on the subway, buses, taxis, and of course walking all over. I also travel by air occasionally, although I haven't since purchasing this bag about a month ago.So in that last month I've had plenty of opportunities to put this bag to the test. And in every respect, it's passed those tests. It took me about a week to get used to the new system, but since then I have been continually impressed by Everki's thoughtful layout, quality materials, and attention to detail.The layout system is perfect for my situation. I can easily organize (and therefore locate) everything I need to function on the road. It's really quite impressive how much can fit in here. It can't accommodate large tupperware very easily, but everything else slides in perfectly: 17" laptop with extra battery, files, mouse and other computer peripherals, tablet, wallet, and all the odds and ends you need to make life on the road pleasant.It's amazing what a difference quality materials make too. The exterior and interior materials are really attractive (love the orange interior), and all zippers and connections are smooth and solid. I was originally looking for an all-leather case, but honestly I find this just as attractive, and it certainly seems like it will hold up over the years much better. Even the handle is more comfortable that other cases I've owned.Overall, this is a most impressive effort. I researched every bag on the market before choosing this one, and I believe that research paid off. Five well-earned stars.
