Being able to use your phone as a credit card is a pretty big deal. NFC readers are normal for many point of sale terminals now and I would love to not have to get out a credit card to pay for something. One of the Lumia phones was supposed to be able to do this, but it didn't work in the US or something because it required some weird encrypted SIM card.
