A recent article from InformationWeek outlines the need for diversity in operating systems as an issue of national security. The over-reliance on the Windows platform has made for an environment of overall vulnerability, and increasing the number of alternative operating systems out there (such as Mac OS X, Linux, Sun Java Desktop System, Solaris, FreeBSD, and others) can help mitigate the risk of attack. I could not agree more. Just take a quick look at the virus reports over the past, oh, say 5 years, and you get the idea of where the problem is. Diversity is a good thing.
