Look, we're as excited about the rapid adoption and potential of mobile NFC payments as anyone, Google, but can we ease up on the sales pitch a bit? If you sign up for Google Wallet, you get asked if you have a Nexus S, and a Citi MasterCard. If you say no, then you get a message saying that you should "consider" acquiring both. Since the Nexus S 4G is a Sprint device, that would mean that I would need to cancel my AT&T contract (or, I guess, have two contracts going) and also apply for a new credit card.
