I just don't like all the white backgrounds in the apps like Calendar, music and note. I was a fan of the material thing(skxxxpxrism) but it is alright now, it is just TOO BRIGHT/WHITE. About the dock on iPhone 4, maybe they can just pre process the color of it for us cuz there is no 3D effect for it. I would be nice if they include a black/grey version for black iPhones, it just looks weird to me for some reason. Maybe thats the reason why they only used white iPhone in the keynotes.
