It makes sense. Once Apple finally relented and gave us larger screens there isn't much more for them to give us. The modest spec bump each year really doesn't buy you much anymore. If you have a 6 or 6s was there any reason to buy a 7 other than the need to have the newest? Not many people want to waste money like that. My not buying the 7 was the first time I've ever broken the 2 year upgrade cycle. I've had the original, the 3G, 4, 5, 6+ and didn't buy the 7+ because it was a joke of an upgrade and the 6+ is more than enough. The earlier iterations had much larger jumps in processing capability allowing iOS to do more and more, but now that isn't a whole lot that the last few years of phones can't do to push you to a newer model. Cell phone technology has finally matured and there is no more generational jumps to be seen in the near future. Just like desktops and laptops before them, cell phones have now peaked and only get modest changes each year. How many people buy new desktops or laptops ever year? or even every 2 years? I'm still rocking a Retina 2012 MBP and I love it. Thats 5+ years of use out of my laptop, I see no reason phones won't be the same going forward.
