Not to put too fine a point on it, but you should let the powers that be know
that the acquisition cost is a minor part of the TCO. The major part is in
supporting the machines, keeping them running, etc. With LTSP, you mostly
support one machine, the server, with a little overhead for the clients. If
they get 20 Macs, make sure everyone, and I mean everyone, knows the cost of
supporting them will be 20 times the cost of the LTSP lab. Linux, done
properly, is cheaper in the short run and MUCH cheaper in the long run.
