Earlier quoted context omitted.
A while ago I quit buying new models and switched to refurbished ones. The 7 I had did more or less what its predecessor did (car services, chat, remote camera control) and the one I have now (X or Xs?) does more or less what the 7 did. I can afford the newer ones, but I don't see the value relative to the four-figure cost.
When I got my XS ($1000) it was because I planned to keep it for a long time. It's been a year and a half and I have zero complaints of degradation in speed, battery life, etc. Still feels like new. I plan on keeping it for four years at least. Compare that to the $500 phones of the past that would limp across the two-year mark and it's really not unreasonable.
Best iphone i have ever needed.
