The original claim (GP of the comment you quoted) was: > I think we're getting to the point where the incremental gains we're seeing with each new phone cycle are almost unnoticeable to the average user That's why the comparison between phones of successive years was made. That being said, I'm not disagreeing with your claim that most people will upgrade from older devices.
