Workflow modifications aside, we could easily get away with running Windows instead of Macs in our art department. It's just a matter of prying the $70 mice and keyboards out of their cold dead hands.

It is of course the platform they've been accustomed to all these years.
For us though, the maintaining of color consistency occurs between the press and the customer's proof/existing printing. Then being able to reproduce that consistency time and time again in future jobs.
We do calibrate the iMacs and cinema displays (to the best of their abilities) to match what the presses can produce, but they'll never be 100% dead on with each other. So on the computer side of things, the emphasis is on the CMYK/RGB numbers... Which you can do on whatever platform you want.
