DVCS? I'm sold

As a casual reader of DVCS advantages like git and mercurial, I think I am ready. Motivated by a great article shared by Kit Plummer, I am sold and ready to start using it. Unfortunately, it's probably not going to happen any time soon at work until a) IT supports a mercurial server like they do svn or b) I start a new project were new decisions like language (ruby/groovy) and source control can be made and I'm not hindered by "we are already using svn, why switch" or "I just got comfortable with svn" or "every team member would have to learn mercurial". Reminds me of my favoriate Zed Shaw quote from this article:

"This folks is the classic problem with programmers today. They absolutely refuse to learn anything new unless they can see that learning the new hotness will give them an immediate 200% boost in salary or get them hot honeys at the next conference."

Now that I see that Hudson has a mercurial plugin and Jira does as well, then technically speaking, I can't think of any other reason not to switch.
