Is this maintenance costs for traditional corporate use where your user base has a lot of "where's the any key" users, and you may have hundreds of hosts to maintain. I suspect maintenance costs in a high end company with a handful of high end macs vs high end workstations is quite different note that the production company seems to be using the macs in a peer to peer set up. And thus doesn't have all the overhead of domain controllers, exchange servers etc a traditional pc deployment.
