The posts didn't convince me to switch, they just reminded me it existed. I'm using mutt specifically because I want far less functionality in my email client, probably not for everyone. No contact/calendar integration, moving things is a pain, searching is a pain. I'm sure there are good solution for these issues but I just want to get emails in an inbox and send them out an outbox. If I need more, I move the useful information from the email to a tool better suited for the job (e.g. file system, database, version control).
