That is because you have not experienced the joyous epiphany that is Git.
+1 Absolutely right! Git is the win. Only caveat is if you have Unicode filenames/folders ... Doesn't encode/decode properly on Windows (or at least not from Linux->Windows). Best for merging and local commits though by far.
I've found something better than SVN, and that is GIT. TortoiseGit makes Version Control so much better (particularly when merging two branches from different users). It also makes commit-early-commit-often a methodology to live by. I have many Subversion repositories still, I have TortoiseSVN for managing those if I want to go back to SVN, but GIT-SVN provides me local GIT functionality for remote SVN repositories.
I recommend using either SVN or GIT for source revisioning. I also recommend backing up your repositories often to an offsite location (if you can, otherwise a USB stick which stays with you is a nice alternate backup location)
