Here is a helpful link for those considering, or using macs in a corporate environment:

"The MacEnterprise project is a community of IT professionals sharing information and solutions to support Macs in an enterprise. We collaborate on the deployment, management, and integration of Mac OS X client and server computers into multi-platform computing environments.

This project, formerly named MacOSXLabs, has expanded the scope of its focus beyond deployment of Macs in higher education labs to include Macs in the broader enterprise environment"
