who'd have thought that by now, email clients are not a done-deal. It's awesome to see people still bringing out thick mail clients and people liking them. A few years back everyone rushed to move apps to the web for no-install and no-version problems, now we seem to be swinging back to thick-clients, until people once again realize the challenges of such. As the landscape changes and software distribution improves (for example the app store) it once again opens up the door to new clients.
