I believe this is one of the main contributing factors in people who strongly prefer iOS devices over Android as well. With iOS, there are no options really. You buy high end or you don't buy. With Android, people will end up buying some 150-200€ phone and being shocked it doesn't compare to their 1100€ iPhone.
It's different now with the main Android manufacturers offering 5-7 years of security updates. But for a long time the lifetime of an Android device was 2 (maybe 3) years, where as iPhones offered 5 years (maybe up to 7).
Perhaps not relevant if you're the sort of person who upgrades every year or two anyway. But a big deal if you're not.
