Given these were given basically as a "thank you" for early supporters of the project, I sure hope they sell for a steep, steep premium above "normal" trezors.
Tbh, I would auction them off to the highest bidders, really.
That's not a bad idea. It would ensure that they're truly going to people who are interested in owning them (since they'd be willing to pay so much for them) rather than whoever is able to refresh their browser page quick enough to place an order for one of the twenty units. They'd definitely be a great novelty item for a bitcoin fanatic.
