Glenn Fleishman makes the case for Apple Watch becoming a digital hub :
HomeKit, HealthKit, Apple Pay, AirPlay, CarPlay, Touch ID, iCloud. The Watch is the digital hub around which everything rotates in the new Apple universe.
A phone, a tablet, a car screen, an HDTV, a monitor, a Mac display — these all become the extensions of the same digital identity that the Watch facilitates managing.
I've felt from the beginning that Apple Watch will the center of our digital ID - authorizing and unlocking things around us.
