Somewhat off topic - but I recently purchased a Redoxx CPA Briefcase bag, which I got specifically to use on my daily commute. It is fabulous - really strong, with zippers that are easy to work, a shoulder strap that is the best I've ever had, and good solid zipper puller things (monkey fists, I think they call them). I am so impressed. And that bag can have a lot of stuff jammed in it if I need to.
I don't need an AirBoss - for my travel, which is all leisure these days - I use Rick Steves stuff - but if I got back into the out-Sunday back-Friday rat race I would surely look into it.
