Simpler networking good, but not to detriment of security

Re: Ian Palmer's article, "Why simplifying network security is critical," June 7, 2005:

While I agree with Mr. Palmer’s position that it is simpler to manage a less-diverse network, I contend that this approach may make you more vulnerable to outside attack.

While it is a given that it is simpler and cheaper to manage a system the more homogeneous it is, a successful attack on such a system could be far more devastating. If a zero-day virus written for a specific attack target (say, Windows 2003) is released, and all your servers are of that variety, potentially all of your systems will be nearly simultaneously compromised.
