I have recently moved my company to Subversion from SourceSafe.
200-300 full time developers, for the most part on Windows. We have
big products with long history. And Subversion deals very nice. There
is only one problem -- working copy littile bit slow on large working
copy, but I hope it will imrpove in 1.3.

PS: If you interested we decide to use BDB as backend.
