Forgive me if I'm wrong, but the example the author gives about changing subway to train looks to be a conversation via text.
Does that mean Apple is actually changing the content of your texts? Does that mean that it changes what displays on the receiver's screen based on their locale?
I don't think the "camera bulge" is really a cause for panic. From the picture they showed on their website of the camera, it looks like it barely sticks out.
