Maybe I misunderstood when you wrote, "Means he can turn up for his job straight for the airport, open his case in front of his clients and his colleagues and whip out whatever he needs without the slightest shred of embarrassment. "

If he's a photcopier repairman or some other kind of 'technician' then maybe I could buy it. I took it as a person going to a meeting with a client. ie. a business meeting with everyone in suits and ties.

As for the Zuka bag you show, it weighs: ■Weight (frame and bag): 9.3 lbs
■Weight (with accessories): 12 lbs

I 'get' packing cubes LapLap, there's not much to not 'get'. What I don't think you 'get' is weight is a travellers enemy.
