Apple Watch has NFC - now that is something none of the Android watches have. Don't pull your phone or wallet out, pay with your wrist. But by early 2015, Android Wear will catch up.
That's the single feature that the Apple Watch has that I'm interested in. Over the past year, I've been integrating NFC into a huge part of my daily life (from implants to door locks to smart tags all over my house) and having it in a watch is killer. Just not enough to jump back to the iPhone. Can't wait to see the Moto 360 r2 with NFC.
I'm curious about authentication. How do you make sure only authorized transactions go through without pulling out the phone (which would make having NFC on the watch irrelevant anyhow)?
