This looks nice, but doesn't strike me as a revolution.
What I would love to see is a mail client that does away with the antiquated inbox/sent paradigm. It would be replaced by active/archived. If I send an email, it would appear in my active list until the expected outcome is achieved (eg. a reply). At that point I archive it. Sent and received would sit in the same view (like Facebook, etc), why they don't already on clients is beyond me. I shouldnt have to manage 2 views to ensure I've acted on received and others have acted on my sent.
