And it seems like someone can make the reverse statements substituting iOS for Windows and vice versa, which is what I was pointing out.
Erm just No.
iOS in it's history of 8-9 years, has
never ever made any iOS decice any faster. It incrementally slows things down. Sometimes with genuine new features or most of the time with useless features like blur and slow animations.
Windows Vista was slow, but subsequent versions of Windows from 7 onwards have nailed their animation code.
If you have graphics drivers installed, the animation never stutters even by 1 percent.
Windows softwares from third parties might get slow due to own bloat and try to make Windows slower, but Windows itself is not slow after a fresh install.
The people who are complaining about Windows have some dodgy app, antivirus or downright bloated factory default install from OEM manufacturers.
From iOS 8 onwards, the lag and stutter has gotten worse. It feels like Android 3.0 (before Google's project butter)
For a second, pickup a Google Nexus 5 or 6 or 6P and see how each transition is rendered at a smooth 60 fps.
Compared to that, even my iPad Air 2 stutters at random places, notably at multitasking screen.
The 1-2 second lag while tapping and launching applications in iOS 9 also feels deliberate. Or they broke a perfectly working earlier code while baking in their Touch 3D code.
