For all the talk that I continue to hear about how Windows is not a safe operating system, I'm really glad to see independent groups such as ZDNet putting out studies such as this one:

I love this chart from the article:
It shows that OSX had (on average) roughly 5.5 times as many flaws per month as Windows XP and Windows Vista combined! The staggering number for me is 234 highly critical (or worse) flaws in OSX compared to 27 in Vista and XP combined (some of which look to me to be double counted between Vista and XP).
