I am not talking about truning over control to another department or
computer centre, i am talking about the simplicity of managing a
departmental system, much like an 11/780 with many terminals and moving to
a system of many diskless/dataless workstations and a few servers.  The
administrative costs go up alarmingly.  I am all for people having
autonomy over their own machines, if they want the responsibility of
maintaining their machines and are capable of doing so, or don't care what
their machine is set up like, they just want to use it as is. The problem
that I am addressing is one where the machine users do not want the
responsibility of their own machine administration, they want all the
services available on a centralized system replicated on each workstation,
they want the individual machines to give an environment that really
"feels" like a single system.  All filesystems are visible,
backups/restores are done for them, printers and software systems are
maintained by someone else.

Over here the users want to work on their own area of reserach, some might
consider that system hacking is fun, but most just want a well maintained
computer environment to be provided. The others (mostly paostgrads) get to
play with the system anyway, because we like to cooperate with each other.
For our research users, a centralized computing resource and many
windowing terminals, would be a a lot simpler to maintain than a set of
workstations trying to look like a system.  For our student users, a
centralized system should be the only way to go.
