As of about three weeks ago I'm using Linux Mint 13 with the Cinnamon desktop. I don't even know what half of that means. I'm just doing what comes up by default. It's nice to be back to a desktop that works for content producers -- not that I produce that much content.
[Edit: Cinnamon runs fine on a low-powered computer like a Dell Vostro 1440, but don't try to use Chrome.]
