KitKat was announced over a year ago and debuted on October 31, 2013. iOS 8 has been out for about a week and is a .0 release so that's expected.
With that said, having participated in both iOS 7 & 8's developer preview I think both initial releases were rushed to meet a deadline. Ignoring the problems with 8.0.1, why not wait a week and release that build as 8.0? It's not like there's any "surprise" hardware out there. And no, that's not open ended.
Maybe the hardware guy isn't such a good software guy after all? </snarkycomment>
Fair point about KitKat, but it was never as buggy as this. iOS 8 seems like it has pretty edges, even compared to the first iteration of KitKat.
iOS 8 is more like Android 4.0, both in terms of features (or the lack of) and the inconsistent way these features work, including the integration with things like 3rd party keyboards.
BTW I really really wanted to like iOS 8 but it looks like the iPhone 6 will not be my daily driver for now. But I do love the camera.
