The amount of work to do that in svn compared to the amount of work to do
that with git/mercurial is ridiculous.

That could work, but it'll yield a repository where you have about 2-3
branches per developper (yes, people using git/mercurial often have lots of
features/tests branches) that nobody cares about. Also, storing test
branches on the public repo is just silly imho.

Simply creating a branch and then merging it back was a nightmare with svn.
If you typed your command wrong, or did an error, then everyone suffered of
your mistake. You then had to correct it in a rush before it created
problems for others, etc.

With git/hg, when you do a mistake, you simply cancel your local merge and
redo it again until you did the right thing, then you push.

To be honest, I feel that all the people that "cannot see the advantages of
a DVCS" are people who either didn't try it, or tried it just enough to
reassure themselves it wasn't worth it. Any tool can suck if you're not
willing to *really* see what it's worth.
