So this became a source control war all of a sudden? 
Going back on topic, does source control integration need to be integrated with the Editor, or can it just be with Visual Studio, or can you just use whatever client on your machine? I personally use git, SVN, CVS, and TSVC depending on the project and team, from command line, in cygwin, on linux, on OSX, on VS, and I don’t have much of an issue.
Other than convenience, what is the advantage of source control integration in the Editor? Does it make you that more productive than the alternatives?
