Jonny Evans, Computerworld:

Apple has described the Apple Watch as its “most personal device ever.” That’s not just because it sits against your skin and you can purchase snazzy new watchbands for it; it’s also because its sensors assess all sorts of personal data about you.

And:

This is an intimate device. It’s as much about who you are and what you need as what others need. Think about Apple Pay, Apple Watch as ID, or even boarding a plane thanks to the air ticket in your Apple Watch Wallet and a shake of the wrist.

And:

Does your iPhone cease to function as identity when it is no longer close to your skin? Is your iPhone eventually going to be able to tell the difference between one person and another by the unique beat of their heart? Apple Watch should be able to do just that.

Very interesting post. The Apple Watch has massive potential, especially as sensor technology evolves and the bond between you and your Apple Watch becomes much more intimate.
