At work, I'm stuck on CVS. I'd love to use git, but the people I work with don't really know how to use any version control system properly. My commits are the only ones with commit messages. They don't use tags and haven't heard of branches.
I mentioned git to my boss, but he was hesitant because he couldn't get it running on his Windows 7 box at home (we don't use Windows 7 at work, mostly WinXP). I did a quick Google search and found that the problem is with a changed DLL in Windows 7, and that putting the old version of that DLL in git's bin directory should work, but I don't think my boss tried that.
