FWIW, Facebook is well into the process of moving the bulk of its
development to Mercurial, having started on SVN and Git. For the
interim, there's continuous mirroring to the other two systems with
hgsubversion and hg-git, but features like remotefilelog and hgwatchman
mean that Mercurial is significantly faster so most of our users have
migrated over.

(You'll note there are no absolute numbers in this post, but rest
assured that the repositories are big.)

On the Windows side of things, Mercurial integration for Visual Studio
does exist, but most users lean towards TortoiseHg. Windows support for
hgwatchman is in the pipeline.
