Maybe it's because I've mostly used VSS in the past, but SVN is just so easy and awesome. It was a breeze to setup and also get svnserve running, and now by using TortoiseSVN everything is just a right-click away from a commit, add, delete, etc. I've just yet to find anything that makes me unhappy about Subversion. It rocks! I guess my next step is to have it running locally and version ALL my files. Awesome.
