mutt + offlineimap + gmail is fantastic. When I need to use their web interface it is painful. mu gives you almost instant search, but I almost never need to search email so I don't have that dialed in.
I use a similar set-up, but I had a really bad time making offlineimap sync work. In the end I switched to isync which was easier to configure. It has fewer features, but it has worked out great for me with `Flatten .` turned on in the configuration file.
Yeah. Offlineimap was a bear to get working right. I've heard good things about isync, but I don't really want to touch the house of cards now that it is all working.
