A couple of iPhone camps developing. One interact with the iPhone screen extensively and the other, iPhone becoming more of a manager of resources. I am drifting more and more towards the iPhone being a manager of resources thus, not needing as many of the screen interaction tools. Example, my Apple Watch and Siri now consuming more of my interaction with apps like phone, music, messages, activity, workouts, notifications, to name just a few. My iPhone stays in picket or bag longer with each new generation. The need for cool things like screen quality, size and Face ID, with their added costs are less and less attractive. I see this trend excellerating, as the Apple Watch, Siri, and new devices gain functionality. iPhone not going away anytime soon. Maybe the hub that holds together the echo system.
