I think you're mainly referring to using Google for Mail (as opposed to running and SMTP server). Actually that's what I'm going to refer to - its the one argument I have, using Google for mail gives you POP/IMAP and a great web interface, as well as robust architecture, all built in for cheap/free -definitely worth it. (Note you can just point your mail to google via DNS and still control your domain).
