I could see preferring svn to git because of the simpler model, but cvs? No thanks, a vcs without atomic commits is not much better than snapshot archives, maybe worse actually.
a) SVN seems daunting and complex, tho I didn't ever dive into it. CVS is so simple and easy, a half-arsed programmer like me can actually understand it. Things like git and mercurial are way more complex.
b) RCS is real handy for single files, e.g. a free-standing text file or shell script. But when the thing grows up, it is very easy to integrate the fileset into a CVS repo preserving it's history: move the ,v files to $CVSROOT/$MODULE/.
c) The repository model of CVS is as transparent as it gets.
d) The keywords like $Id$ are really useful.
e.g. I keep my system configuration in "~/Checkouts/system-config", and I have a script that cp's the files to appropriate locations using a map file. When I'm not sure if the active config is not up to date, I can verify very easily. And I can be sure that dirty files won't be active as long as I don't expressly copy them. I know that SVN has this too, but I find CVS easier to use in general.
I guess for fast paced, very active development, yes CVS is sub-par, but for personal stuff, or for something that is patched say at most two-three times a month, it's O.K. It boils down to personal preference.
1, atomic commits. I edit ten files, that's one checkin, rather than the per file checkins of cvs. On a low volume project, not a big advantage. if you've ever conflicted on a bigger project with cvs, it can be kind of a pain to resolve. seeing the whole commit of the other guy is helpful. If you don't run into this more than, say, monthly, it's not worth it.
2. offline diffs. svn has a whole copy of the repo, so you can compare history even if the central repo is down, or you're working from the beach. This one is pretty nice regardless.
svn is a pretty nice upgrade, if you're working with a distributed team.
I believe that one should use the best tool for the case, not the overall best tool in every case.
That said, I'll give a look at SVN. I can consider switch when I have the time if it is easy to import from RCS, because I do use it a lot here and there, mostly for plain text documents. I do not like maintaining unrelated things in a single repository.
If you're learning for the sake of learning, i'd dig into git. i'm getting better, but some cases still frighten me.
Well, nearly everything moved to git. I've used it for a while, mostly commit/pull/clone. I actually moved to CVS from git :) It's a bit like perl, git, you either need to be an expert at it, or else you can get going, but at the end you create a mess.

Mostly, yes, but mostly because I don't really need that much more than recording my history, and occasionally looking at what I did in the past and more rarely working on short-lived branches. But there are a couple tools that if I ever code them up, I will make opensource. Tho if I ever do, and they take on, I'll use a 'just send a patch on the mailing list' approach. I believe it's easier to deal with. No flamewars on VCSes :)
There were plenty of things I didn't like about SVN (separate folders per branch? yuk), having used CVS, and didn't find it 'trivial' to pick up.
