Same. I don't like each and every proposed solution that all the recent email clients have, but I live a life which, like it or not, involves a hell of a lot of email. So against all odds, seeing people trying to seriously tackle email from different angles is exciting.
I had a long conversation with a friend over lunch once where we both started by imagining a severely improved client, and eventually concluded that once you had traction with that the real benefits would come from a severely improved protocol. A lot of what makes email suck seems pretty baked into it historically.
