Here is a (simple innacurate) list of what a DCVS can do that a VCS usually
cannot do:

   1. commit when you don't have a working internet connection
   2. see the diffs between two very old revisions without a working
   internet connection
   3. don't wait 5-10 seconds to see the diffs between old revisions
   because of the internet latency
   4. use branches and merge them without fear of making mistakes (because
   you can simply undo what you did before pushing to the remote)

About the two first point, if you suggest that you can do it with svn by
setting up your own local svn server and do a deep copy of the svn server
and then using that one to commit/view diffs when you don't have a working
internet connection this is just too much work compared to a DCVS for it to
be a real alternative.

Point 1 & 2 are more important than you think, it frees people to hack &
work on the project without bothering others on the central repo. They can
hack & throw away changes and only present stuffs when it's ready (because
you can throw away unpushed commits).

Point 3 is not crucial but in the long run it's very nice to have, now when
I switch back to projects using SVN I get frustrated having to wait.

Point 4 is the real important point here imho.
