And while you link those sunspider tests,I have benchmarks proving iOS 9 degraded launch times for several apps.Videos show that iOS 9 almost always is slower than 8.4.1.Now lets look at Apple's claims
Those benchmarks of yours dont indicate responsiveness do they?App launch times do and this is how iOS 9 fares in that area
5 wins for iOS 8.4.1 and 2 for iOS 9.Whats the point of improving INVISIBLE Sunspider scores when my phone takes longer to open the browser which uses it?You degraded it in that area effectively ruining the customer experience there
Do your benchmarks prove more reponsive scrolling and animations?Not by a long shot.Scrolling is HORRIBLE in apps and animations still stutter in mobile data apps,spotlight and when you rapidly swipe through homescreens after terminating apps
Microsoft is supporting multiple Windows versions down till 2009.Google is providing security updates for 2 or more releases.Providing security updates to iOS 6 on a iPhone 4S should be nothing to the richest tech company in the world.
They designed OS with 2GB Iphones in mind and simply backported it to the 6 without doing any optimisations for it.Now you tell me why would they do such a thing
