I still don't see why we need NFC so badly. There are so many different electronic payment options already that don't tie you down to specific devices and security holes.
I would think there are enough people out there who would find this rather convenient. I have my phone with me 99% of the time, yet sometimes I forget my credit card in a pair of pants or another coat I am wearing.
Being able to do more with one device simplifies life for some people. If it were available on my carrier, I would sign up right away.
