For many there were more serious issues (mostly on stability and functional side along with some performance) with the initial versions of it it in comparison to animation stutters.Was iOS 8 really an unstable mess? I've had my air 2 since last November, I really do not recall it crashing or being unstable on any of the versions of iOS 8. The Air 2 was a beast of a performer out of the gate. I've spent about 10 months using it with an iOS 8 version and now about 2 months using it with a version of iOS 9. Its crashed about same number of times now, zilch.
