But what clearly is happening is that the phone is becoming the new tablet: a fairly big screen that’s great for photos, maps, web pages (although who uses the web much, anymore?), video/movies, Office apps, and generally viewing and editing content of any kind.
And the Apple Watch is the new, always-at-hand device that you interact with all day long (perhaps to the chagrin of your coworkers and/or lunch date).
Interesting thoughts. I'm looking forward to seeing how Apple Watch impacts on the way people use their iOS devices.
