An HTC One with a stock Android is coming soon (http://www.androidcentral.com/google-edition-htc-one-coming-...).

As for the camera, I don't know the quality of the camera in any iPhone. But I think the camera in my Nexus 4 is good. It's not very good, but it's not ugly. I'm also not a fan of large size phones... Before. But when I tried browsing using Nexus 4, I felt that I don't want to have a smaller screen again.
