While i too installed it on day one. I still wonder what the major version number change was for. The switch app screen is different but i can't say i like it better. On my iPhone 6 i find it too sensitive i often have trouble closing the right application.
And what about the changes to Siri? In the german language mode Siri still sounds consideribly worse than english speaking Siri.
Asking Siri about german football results? She has no clue about it. Telling Siri to play even a famous classic song from Apple Music? She will not understand a single english titled song at all and tries to interpret any english as some meaningless german gibberish.
When i asked her to play music from "Kaiser Chiefs" she told me she couldn't find anything from "Kaiser Cheese".
At least the new font is better. But that should've been there since iOS 8.0.1.
