A bitcoin-accepting vending machine would be very cool, but that requires that you live near one. Setting up shipping seems a lot easier than creating a nation-wide vending machine network.
Good point. Managing cash for a vending machine with high-value items seems like it might be a pain. I know there are various ipod vending machines around, but I assume most people use a credit card for those. But I suppose feeding some 20s isn't too hard.
