Overall, I love the bag. It was an adjustment at first, coming from a more conventional laptop briefcase, though as I've lived with the Rickshaw bag I've been liking it more and more. It is my first choice for the daily commute to and from my office in downtown Pittsburgh. It gives plenty of protection to my laptop and has room inside for my notebook, power supply, and computer accessories. Not a huge amount of room for files etc., but I have been getting by. Like the two zippered outside pockets, they have a lot of room for the easy-to-misplace smaller stuff.
I do go back to my Briggs and Riley "TSA-approved" briefcase for air travel, however -- the Rickshaw bag is not "check-through" and I have to take the laptop out for security check.
I think it might be improved with a second non-zippered outside pocket. I'm always coming home with my hands full and need someplace to stash magazines and mail for a few minutes until I get upstairs -- when I zip the stuff in the outside pocket I tend to forget about it. And, maybe a small zipped pen holder on the front panel.
But overall the durability and solid construction of the bag more than makes up for the few features that I wish it had.
