Agree entirely. My point was really directed at the situation we're all in regarding cross platform dev tools. We settled on SVN as its the only thing that's fairly easy to get running cross platform as we have both windows and Linux machines online. We also need a centralised repo due to the nature of our work that has strong authorisation against LDAP (our AD).
Now we're actually looking at git and TFS as a forward-looking solution.
I don't think your proposal to use SVN instead is very helpful, though. We run a very heterogeneous network, working on a lot of different projects. "Just change your entire development platform" isn't exactly a constructive suggestion. We also routinely use Git on other projects, and we've never had any trouble setting up shared repositories in those cases. While it does rely on installing some UNIXy tools, and that is indeed more hassle than it needs to be, everything pretty much works once you've done that. Moving everyone onto real Linux workstations is a non-starter, because there are way too many professional software packages we use on Windows without anything in the same class available on Linux.
