I think there is a certain segment that does, yes. Always has been. I'm a biennial upgrader myself, no worse for the wear. This is an upgrade year for me, but w/ no subsidy, I'm saving my $ and skipping this year waiting for the supposed iPhone 8 SuperDuperExtravaganza Cool As Space Rocks Anniversary model. I don't see the 7 as "essential" even for people like me with a 6 unless their battery is zapped. I was a tiny bit tempted with the 7+ b/c of the camera, but my iP6 works fine so difficult to justify when something much more advanced will be out next year.
