vmail is a Vim interface to Gmail
A wonderful one, at that. Setup is simple—a three line config file is all you need—and it makes blazing through lots of mail a cinch, assuming you already know your way around vim. The only downside I can spot is the viewing and sending of attachments, which is a bit fiddly.
Purists will no doubt be muttering ‘Emacs!’ under their breath, but I can see a lot of mutt and sup users switching to vmail.
