I’m going to start using my own domain address for email 100% now. I’ll still push it through Google Apps premium because I love using Gmail. But if Google ever kills off Gmail then I still have full control of my email address. This is good advice in general, regardless of which email service you use. Even further, it's good advice for any service you use that has a public component. I love tumblr, but if they were to go out of business tomorrow then foobar.tumblr.com isn't going to mean much. If you're using it as the backend for a blog at your own URL though, you can switch services without requiring your readers to change their habits. Whether it's email, blogging, or anything else, I think maintaining control of the entry point(s) for any publicly facing services you use is really important.
