Quite a few... Here's all my extra repos (not all are PPA).
Google (though I don't use anything from that one at the moment), Medibuntu, MkvToolNix, NX, Opera, Pidgin, Shutter, Ubuntu Tweak, VirtualBox, and Wine. I think this is a really great way of distributing software! Hope to see more people distributing their application through PPA (or an off-site Debian repository) in the future.
