Does anyone know any good alternatives to Gmail? I briefly looked to switch back when they released Buzz, but there aren't any good competitors that match Gmail's ease of use, spam protection, and (previous) speed. Seems like it'd be a good opportunity for young, hungry startup. I think I'd pay $3-5 a month for a really solid email service.
