It was my pleasure to talk about version control systems: svn (subversion), hg (mercurial), and git at the NWVDNUG.  It was a great discussion about the value of DCVS (Distributed Version Control Systems) vs. Centralized Version Control Systems.  We also hit the main purposes of source control: (1) to facilitate collaboration among developers and (2) keep an audit history of the code changes.  Our purpose was a paradigm change, so our content was really driven by slides, the corresponding discussion, and the questions and answers we delved into.  You can download the slides from SVN-HG-and-GIT.zip.  Enjoy!
