When I see proper Exchange Support (using Exchange Protocol) in Snow Leopard then the built in mail app will be more useable. Until then there are gaping holes for Exchange support and it's flaky when using Exchange servers across IMAP.

If the support was good today they wouldn't need to highlight this as a major upgrade for Snow Leopard.
