In both ClearCase and GIT (and more so in ClearCase) you pay for it by
requiring "someone" do constantly merge stuff to some "stable" mainline.
Moreover, the per-developer branch model is just one way of using
ClearCase and IMHO one of the more broken recommendations.
I once worked in a company where one of the teams used exactly that
approach and had constantly broken builds because one bit or another was
not properly merged from developer-specific branches to the mainline.
When I asked them why not use a little less granularity in their
branches, e.g., at least per-task or per-bugfix, not per-developer, the
response was that "then the developers would work more slowly because
they'd have to worry about other peoples' commits." QED.
(You can get the same effect by creating a branch for each developer in
Subversion. You can imagine the horror that integration then becomes.)
(And just FYI, ClearCase for example /does/ provide a mixed-revision
working copy model.)
