A Complete Farce
This is a complete joke - Part of Apple's mantra is it has a closed ecosystem so it can maximise control over hardware and software. They have a small range of 100% compliant devices to maintain. Compared to other operating systems with more complexity (and smaller profit margins), Apple's complexity issues are highly manageable.
For models like the iPAD2, they should have put a ceiling on the operating system and provided security updates at a minimum. Block App Store installs for products using features which exceed the device's capabilities. Every update is degrading the performance further. "If you think it's slow, maybe you should upgrade" is not a sensible technology strategy. Mind you, they're still making ridiculous profits, and people (like myself) are still buying their products - so hey, what do I know?
