I've had an Empire Builder since Dec 2007, purchased at TB's most excellent factory store. In the time since, I've been through a couple of jobs and laptops, with variously more and less travel, and the EB has been a champ.
The current position requires that I carry two machines - an older Dell and current Lenovo - two phones, and various accessories (power supplies, USB gear, cell-data card, et cetera). I'd been considering replacing the EB with a backpack, but found that everything fit more or less neatly into the EB. It's heavy but it holds everything and then some.
It's had about 110k air miles since I bought it, and it still looks brand-new.
Way to go, TB. I can't recommend this highly enough.
