Tortise is awful. Aside from it's constant integration with explorer (Oh, look, I can add the recyle bin to source control. WTF?! Just active on that particular directory) just try to create a new file, watch its status change to add, now, before comitting,
rename it. Now commit. And watch it eat the repository, so you have to cleanup and manually delete the original filename via the respository browser.
I'm sure SVN is a decent server; but I have yet to find a decent PC client.
