Gee Modern Technology Works

Was at a Starbucks this afternoon to get coffee, a deviation from my usual routine of getting coffee at the Starbucks in the local Safeway. Was struck by the guys ahead of me, both of whom paid by using their cell phone (I've no idea which one). The Times today had an article on Google Wallet, which makes your phone into a credit card.  I've no idea whether the guys I saw were using that, or some Starbucks application.  Anyhow, it's amazing.
