There has been much debate lately over Total Cost of Ownership (TCO) of Linux vs. Windows. This ZDnet article comes down on the side of Linux: “One of the things that Microsoft is starting to lose out on now, and I’m not sure they realize this yet, is that they still claim Windows administrators are cheaper,” Robinson said. “But the flip side of the same coin is that if one of my administrators on a Windows environment can manage only 10 to 15 systems at a time, but my Solaris admin or my NetBSD or my Linux admin can manage 1,000 servers at a time, I need fewer admins. Sure, the salary’s more expensive, but I get more life out of them.”
