I've been using git for a few months now. Like all the best dev tools it has slowly permeated my workflow to the point where I'd feel pretty crippled without it. In fact, I don't think I would ever go back to a centralized system like svn at this point. In a pinch I'd fall back to using git locally and then using the appropriate git-to-foo integration to push my local changes from my git repo to whatever the centralized repository was.
