I enjoyed reading this. Great post by Karen and observations by Bill. My take on this - Apple Pay is here for the long haul, to go after Payments around Connected devices (Watch and Phone integration is probably a POC to show that it is feasible). Demo on the stage around retail use case is more a distraction, functionality where PayPal does it very well already. Payments interfaced with connected devices (IOT setting) - I think there is lot of room for innovation, and Apple Pay is just the start
