Re:Windows. (Score 1)

TortoiseSVN is the only GUI SCM interface I've ever used that I actually found preferable to the command-line. More powerful than the SVN command-line tool in many respects, and easy enough to use that we even had the marketing folks at my last company using SVN thanks to TortoiseSVN. Now I'm back on Linux, FreeBSD, and Mac OS, and I can honestly say that TortoiseSVN is one of the very few things I miss about Windows development.
