> Android for example has clearly a bunch of bugs where some stupid slow animations cannot be tured off. Yes even with turning off animations in accessibility and via the developper options.

I recently found out about Android's animation disable feature and holy hell it made my phone feel so much more snappy and responsive to input. But as you mentioned there are too many bugs - one of the more annoying ones is that loading wheels (which I would prefer to keep because you have to wait anyway) are not animated. I'm tempted to use it anyway. Hopefully in the future Android will add some sort of categorization/prioritization for animations so things can be tweaked more.

I may be in the minority here but I am kind of annoyed with how "juicing" the interface/experience seems to be kind of bleeding over into general applications from the game development scene. It does make sense for games and some apps but in general I don't need animations and tweens attached to every button on my phone.
