At least Google still lets you download your mail(imap it) so keep it updated (your local mail dump). When you need to leave Gmail(or even Google Apps with your own domain) you'll have everything other Gmail chat. There are certain things you might loose - access to those sites which used only Gmail sign-ins - Gmail chat (Calendar and contacts are not a worry but keep it dumped , maybe in Dropbox or Outlook, anyway) - IF you are comfortable with handling a server (sth like Webfaction or a VPS) you can do a lot of these things yourself: mail, calendar, blog, contacts Bonus tip: Seems you are new to these things I would advise you to backup your entire computer along with all these data :-)
