A wallet contains many different things that can be added and subtracted at will. If this Coin thing is to be used as I think it is, it is all your cards, all the time. I can't just bring one card, it's all of them.

Not to mention the fact that now one service has all of my cards and their information? Coin better know what they're getting into. I'd prefer the hassle of many sites than one with everything, just not worth it to me.
