Never used it. I think spying on my users (with the help of Google) is unethical.
(FWIW, I did do a project for a client once which involved extracting data via the Analytics API. It was very easy to do, and all the metrics were there, so it seems possible to make your own chart without requiring Flash. Hell, there is even an in-browser Javascript Analytics API and many in-browser Javascript charting libraries... so you could probably even do this in the form of a bookmarklet or user script!)
Heh, spying is a strong word. Without GA I would have had a harder time figuring out that more of my users are from Spain than from the US for one of my projects.
Thanks for the info. I knew of their API but haven't used it yet.
