FCP and DvD authoring for less than a squillion dollars reigned on the Mac, but hardcore Pros had made a change, because 3d software worked on a PC better???( Macromedia products) or should that be was only available on said machine.<<

Another very limiting factor I find is that a lot of "IT" departments are, to paraphrase a colleague, actually more like "THAT" departments. They don't know Macs and are terrified that if you got one they would be forced to maintain it. And so they would rather spend ten times the money on (deliberatly) crippled PC software that does not one tenth of the things that the full blown Mac stuff does.

Of course most professional Mac users do a lot of our own maintenance and keep humming along nicely while the rest of the office falls apart under the weight of viruses and crashes and crippling imposed by the THAT department in order to stop the viruses and crashes..

I dunno. Watching the mess that is Windows I'm sort of with the guy who said let's keep it a secret.
