Oh wow! I got one a few days ago. =) I picked it up on my way to the airport for a trip I just got back from and I immediately set it up as my wallet. I love it! I think I'll be buying more. Possibly an extra for me and one for my boyfriend. I never realized my wallet was such a cumbersome system until I tried something new.
ETA: My boyfriend actually does want one! Which is exciting because I've been trying to figure out how to convert him to Tom Bihn stuff. Any idea when these will be available to order? I should be ready to make my Brain Bag order any day now (I'm vaguely half hoping the the shop bag will be offered in a new color again which will give me an excuse to go ahead and buy it).
