I upgraded to a 6s (from a 4!) as soon as they came out. The girlfriend got a 7 as soon as they came out, then got a 6s after she broke the 7. Neither of us see any reason to upgrade any time soon (we both buy our phones outright so that's a nice chunk of change). I would like an iPhone X -- just because it's "cooler" -- but I really can't justify spending that much for it when I have a 6s that works just fine.
