I've never seen a unix shop - pure or otherwise - set up as Ted
describes.  That's pretty much the X-term model, and I have seen sites
that use a lot of them. I've also known people who ran their X window
manager on the server because they got quicker responses that way, but
that doesn't make it a common practice. The advantages that accrue to
centralized servers for home directories, mail, print, SQL, ans such
like exist just as much in Unix as they do in Windows. Having the
ability to do things either way is a benefit but you sometimes wish it
couldn't. For instance, that thought is *very* near while walking the
halls trying to find the bonehead who has configured his system to
talk directly to the network printer instead of your print server, and
is repeatedly sending a job that's crashing the printer before it
identifies him.

Unix has those Windows presentation programs, in some cases since
before there was a Windows market worth noticing. That you can run
them either on your desktop, if you've got a nice fast box, or on the
CPU server in the machine room is a great benefit.
