What to do after Google Apps for Your Domain?

Friends, I have been caught by the end of Google Apps for Your Domain, or whatever that program is called. My entire online identity is tied to my email address lincoln@lincolnmullen.com, which is a GMail account. I have Google Docs, calendars, OAuth authentication and so on tied to that account. What should I do? It appears that Fastmail is the leading candidate, with good migration support from GMail. Any other possible email providers? Any considerations I am not thinking about?
