I converted one of my software projects over to Subversion (instead of CVS) last week. I haven't had an opportunity to move directories yet, but I already love it.
On a similar note, I adore Debian. "apt-get install subversion" -- how much easier can it get! And everything works great right away. The Subversion manual is big and easy to read. I was converted in a whole 15 minutes, and the "cvs2svn" script that comes with Subversion made sure I didn't lose any of my previous revisions. The whole procedure was more painless than lying in a big pile of feather mattresses.
Go Subversion! I can't wait for a 1.0 release. Here's hoping CVS will be replaced entirely, all across the Internet.
