Well I don't know about mercurial, surround or clearcase, never having
used them, but I use Subversion and I've played with git (and bought the
book!), so here's what I think:

In git, forking is encouraged. You copy the repository (well, you clone
it) and it comes down onto your PC. You now do your work, fork the
repository, do your own thing, whatever. All changes, additions,
deletions etc that you commit only commit to your local PC's repository
- the one you cloned is not affected and, in fact, you can do your work
offline - on a plane for example - and not have to worry about needing
an internet connection when you come to commit.

In subversion, a commit must talk to the repository.

Mercurial, I think, is similar. As I said, I haven't used it yet, but
I've downloaded the free book to get a heads up on the matter.

So, out there in Linux land, all the developers have their own copy of
the main Git repository and do their work exclusively on that. At some
point they can push their changes back to the main git repository, or
Linus, should he wish to, can selectively pull (I think) changes into
his main repository.

There are other ways of working with Git, the QT guys allow you to clone
it, but no pushes - a repository admin at Nokia merges changes that have
been made/submitted.

When all is said and done, it's just (!) a version control system that
allows you to do all your work offline whereas the non-distributed
systems, subversion, cvs, etc, require you to be online when updating
the repository.

In a nutshell!
