We have had the EDC threads...but I wanna see y'alls "business case". This could be your portfolio, briefcase, gear bags, etc.
Show me what you carry for your "Business"
I've been business carrying forever and had everything from numerous Tumi bags to Army surplus but the best bag I've ever owned is the Maxpedition Kodiak Gearslinger
I can fit everything for work including laptops, cords, power, extra batteries, etc AND 3 days change of clothes in this and still fit it underneath the seat in front of me on the airplane if a hot chick needs a place in the overhead to put her huge bag :-)
They are also a site sponsor I think and from the 1 time I had to contact them, great customer service.
