Nice. One comment. I think the world is moving away from totally flat. For me the rounded corners to indicate touchable object still requires context to make sense. Here we using hackernews with the same approach, however, I never really liked the idea that users are mature enough to implicitly know what is action or nav. The demo page uses a green button for scroll, download and href. Which, while this is clearly example usage, highlights my concern. The button metaphor should indicate change, think before you click. Vs link which you might expect to take you somewhere but not have an "action". I feel like depth expresses this difference because of the reference to the realworld button. Not sure what the majority of users feel, thats just an IMHO.

Looks good on the device i'm using. Non-standard android.
