I bought physical Bitcoins from Memory Dealers in early December to give as gifts to co-workers. I paid via credit card. Because of the CC fees, shipping, etc (all of which is fair for MD) they cost about $6.10 each. Bitcoin at the time was about $3 (my memory may well be wrong).
But it was awfully cool to pass out those coins and say "Bitcoin was $3 when I bought this, but now it's $6".
I see that many of those co-workers still have that coin on their desk. But we're a software shop, they know what cryptography is, what peer to peer means, and we use LOTS of open source, so I hope that at least 1 or 2 of them will "see the light".
As far as MY workplace goes, if we could get some Magic The Gathering tie in, we'd get them all!
