Subversion is still my favourite VCS for collaborating on non-source data. I.e. cases where you typically exchange documents over email/dropbox and use extension-based versioning (e.g. report.v22.final.docx). Subversion keeps all data in one repository nice and tidy. Works well with binary files. Allows easy subtree checkouts. Plus, explicit commits make it easier to track progress without having to dig in your mailbox.
