Awesome video. The music got me kind of perked up for the day. It almost made me forget that nobody uses Google Wallet. We've run an ecommerce store with a decent amount of throughput for about 5 years now and I think we had 1 person try and pay with Google Wallet (and she was a Google employee and friend at the time).
I'm probably off on the whole thing here, because the examples in the vid show it as sort of a way to make good with your pals and not so much for ecommerce, but being an old timer, I sort of like to leave my money transfers to people that specialize in it and not as an add-on to my email client.
