Agree 100%. Two anecdotes that show how far we've come in the last few years: * Working on my laptop on the train the other morning I cd'd into an old source tree that was checked out from subversion a few years ago. I was brought up short by subversion not being able to tell me the revision history, what with it being unable to connect to the repository server. * I also recently needed to checkout an old version of Rails using a rake task I wrote a few years ago, and discovered that Rails subversion repository has gone away. The revision history has moved across to github, but scripts will have broken and existing subversion checkouts will have lost their history. If you go with a centralised VCS, you will get burned at some point by being unable to connect to a repository, either temporarily or permanently.
