"The Bihn system seemed pretty smartly designed when I first packed the bag, but now at the tail end of my trip, I can say that it's friggin ingenious! My company's version of "business travel" is probably one of the more rigorous things one can do with their time. Most weekdays consist of waking up at 6AM, getting dressed, re-packing your suitcase, visiting with customers or co-workers until 6PM or so, then driving or flying to the next city. So, it's really important to have ever piece of your travel arsenal designed well enough to make packing, retrieval, and, of course, carrying as easy as possible.
Fully loaded, the Smart Alec held all of my workday stuff plus a spare change of clothes in a packing folder (should luggage get lost in transit), and weighed in around 17 pounds. I'm happy to say that I have no back strain or fatigue after carrying it through Budapest, Vienna, Munich, Stuttgart, Dusseldorf, Paris, and Madrid. I highly recommend it!!!"
