I can't even get updates for my original iPad any longer. It's stuck at 5.1 or something like that.
I installed iOS 7 on my iPhone 4 and the code is so unsuited for that device that many UI elements don't respond to touches and gestures made at normal human speed. You have to slow down by a factor of two or more for things to register. Trying to double-click the home button is an exercise in frustration.
It's definitely not FUD that apple releases OS upgrades that don't do well on older hardware.
That's absolutely true on mobile platforms, which have made major advances in both performance and architecture over the past couple of years.
It isn't true on PC hardware, where a modern kaby lake i5 performs similarly on desktop tasks to a a 5 year old ivy bridge i5. PC hardware has advanced tremendously in power efficiency, but much less so in performance.
