I got the card but haven't bothered to activate. I'm genuinely hoping that +Google Wallet
will add functionality, like being able to use cards in your account.
COIN is interesting, but there are some issues. For one, it violates the ToS of most card issuers. How do you think they will respond to you duplicating their card and using one without their logo? Two, it's expensive. For those unwilling to be early adopters, it's too expensive. Three, it's a startup. Remind me how many of those fail?
