I enjoy the Google interface and spam filtering, but don't want to be dependent on them. So I've been transitioning to a new address on my own domain, and just auto-forward the mail from my server to gmail and reply from there (using my domain). I also download my mail via IMAP monthly so I'll have a backup in case I ever lose access. There's also a fringe benefit: I can run spam assassin on the server, set to filter out only the spammiest of spam. That cuts the quantity in gmail's spam folder down to a level I can manageably look through on occasion for false positives.
