Fluent - a paradigm shift in Email Management Interface?

I see so many articles talking about how email is dead. I could care less, but if there is one indicator to me that email is dead is that nobody is willing to create their own email service anymore. Instead, a typical email start-up will just be skinning Gmail.

I have been contemplating on moving away from Gmail, and that's the only reason I only clicked the link. Of course, there is no way of getting away from Gmail with this service.
