"Only" gmail? But isn't email the most important part of your online life? I moved away completely from Google. Fastmail.fm instead of gmail was one of my first moves. And I never looked back...
See my reply to pron, but yes. Everyone, and all business, that I want to know me are in my contacts on another service. I also use Thunderbird, and PGP when possible, with my gmail account so at least I don't see any advertising.
