I really hate websites like this one. It presents data in a one sided manner that doesn’t really help you decide anything. For example if you look at the charts Windows “appears” more secure because they patched fewer problems. Well, that doesn’t really mean much. Because you don’t know how flaws there are out there to patch. Which brings up something I never really see mentioned. One of the benefits of open source is you generally can pull up a list of all known problems. With closed source your only privy to a list of problems they will either admit to or allow you to see. So the question then begs, How many problems does MS know Windows has but hasn’t admitted to yet?
Just remember to look at all the fact before you deciede.
