Love the new Mail in Lion, it's a huge improvement. But Mission Control sucks and totally messes with my workflow, which makes heavy use of Expose & Spaces. I would be totally satisfied staying with Snow Leopard, if I hadn't tried the new Mail, which I know have to have! It's much better than the SL alternatives Postbox and Sparrow. Do you think there is any chance the updated Mail will be made available for SL?
