I'm not sure I agree with that; I mean I use TortoiseSVN and before that TortoiseCVS as my main interface to version control, and have done for the last 10 years. It works perfectly and I don't feel I'm missing the command-line at all. (A goal of Subversion was that its command-line commands produce output which is both easily parsable by humans and machines. But still, I never use it.)
