Just to note, one of the design goals of Subversion was that the command interface be backwards-compatible with CVS. So if you switch over, you won't need to relearn how to use your SCM, just remember to type 'svn' instead of 'cvs' (or alias cvs=svn in a shell startup file). The only thing you need to get used to is that you are now able to rename and move directories, as well as do a bunch of other stuff :-).
