Well this is a pleasant surprise... the ZTE Orbit will have NFC (Near Field Communications) capabilities:

I don't think NFC has become widespread enough to make it a "killer feature" but it seems like things are headed that direction. If you plan to have a phone for 2 years it would be nice to have NFC since within 1 year a lot more places will likely use NFC. Still... I think we're 2.5 years to it being anything regular/normal.
