Once again, I dunno. My observation is that non-software industries are leery of git. My last four clients have all used svn or hg. So am guessing that it depends on the need for centralized control and who you have available to run these systems.

I do mostly hardware engineering -code is a secondary by-product. So my tools poorly represent what most of you need. For my colleagues and myself, Hg is it where distributed stuff is required. For my personal stuff, svn is it.
