Scott Ambler acknowledges that for many people, rhetoric isn't sufficient—they want to know how many people are actually doing this Agile stuff, what they are doing, and whether they are actually benefiting from it.

Most respondents had experienced at least one really bad experience - resulting in much lower productivity or quality, or drastically increased cost. Still, across the board, respondents reported overall significantly better quality and productivity. More knowledge of Agile did seem to correlate with better experiences.
Ambler's survey used the mailing lists of Software Development magazine and Dr. Dobbs' Journal, so he acknowledges that the results may be a bit optimistic: respondents may be more aware of new trends in IT than people who don't read such publications. None the less, Ambler concludes that Agile approaches do work in practice, and that these methodologies are gaining traction.
Ambler has published his conclusions on Dr. Dobbs Journal, and has also made his survey questions available, as well as his raw data.
