Right, so you already said it's skewed, which these fan based sites are. Out in the real world, it's a differing story.I didn't ask for your help.I am telling you what a normal rational person would do.No one is gonna dump $4000 worth of ecosystem hardware for a $800 phone.
9to5 already did. 70% said the new release of iOS 9 crippled their old devices
As far as a "normal rational person", except for your 6, I havent heard / seen in the real world a crippled device. My iPad 2 runs fine under iOS 8. My sons 6 runs fine under iOS 10, as does my two 5s. So we're are not "throwing out" anything. And I would dump $4k worth of anything if I were that unhappy with it.
