One huge thing you missed is device pairing. Nokia already uses NFC to pair their wireless accessories (headsets, speakers, etc). With wireless charging, it makes docks obsolete http://www.youtube.com/watch?v=upo-e692lRg
Using an out of band channel, such as NFC, is defined in the Bluetooth secure simple pairing specification.
Agreed. While a lot of other uses may be more profound in the long run, this one seems most achievable in the short (least amount of security concerns and consumer education).
