HP Eying NFC for Future Phones
NFC vs TouchStone Technology
If this is the case I'm curious as to if the Pre3 was delayed to incorporate some new TouchStone/NFC tech. That is most likely wishful thinking as I doubt they'd ever change a product so late to final spec.
I think both of these technologies have mass appeal as I'd love to be able to data with friends by just touching NFC enabled devices together.
