You are completely right on both. I'm sorry, my mistake. Regarding the Send button, or lack of thereof, it is much better blue than gray but, as you said, it is not as intuitive as a button. There is a lack of perceived affordance. It's one of the top 10 mistakes in application design that Nielsen[1] points. Of course Nielsen can be wrong and Apple can be right.
