Hi, that MS article is just marketing fluff. Here is a less biased viewpoint: http://arstechnica.com/news.ars/post/20080425-study-70-percent-say-red-hat-more-secure-than-windows.html Its further interesting to note that at a CanSecWest conference earlier this year, researchers were given access to 3 machines to attempt to hack. The OSX laptop was compromised on day 2, the Vista laptop on day 3, and the machine running Ubuntu linux wasn't hacked into at all.
