One of my clients actually said to me, at the closing of a project: "I don't know if you take bit coins, but I'm gonna go see my bitcoin guy in a few. I don't like to buy online. Anyway, if you want to be paid in bit coins, let me know! Otherwise I'll drop the check in the mail tomorrow."
(that's paraphrased a bit, as I cannot remember the exact wording, but the meat of the quote is the same.)
And if I don't want the anonymity premium these guys make it sound like it's difficult to do instant trades... Meanwhile I've got Coinbase on Instant Trade up to 10 BTC per day, and other exchanges have similar options (if you choose to verify with ID/Bank Info/etc).
You don't, this one just scans your palm, which seems a lot easier than the runaround necessary to create an online account anywhere.
Since there are no 'palm databases' linking your palm to your identity, seems pretty anonymous too. It is only to ostensibly prevent any one user from going over the daily transaction limit. (As an aside I personally don't see anonymity as a big issue most of the time anyway).
