Moving back to Windows from Mac

Infoworld has and article about why one Mac evangelist moved back to Windows for work. I am glad that one engineer sees the light. IT shouldn't have to work twice as hard for a tiny faction of rebels. This has been my experience everywhere I go that I am forced to support Mac hardware; Mac users refuse to acknowledge the work they require IT to sustain just for them to run their pet OS. At the end of the day my hourly rate may be a sunk cost, but it isn't free and until it is Mac costs most businesses more money than it saves.
