Especially the fact that Apple's OS security has been solid, all thru the past two decades, with very few exploits, while Microsofts has bee wide open during those period, and Microsooft deliberately chose not to close the holes because they were there for "marketing initiatives".
On Windows a massive industry of malware detection has sprung up and still there are millions upon millions of zombie PCs out there. Meanwhile, despite no such industry on OS X there are no reports of infections in the wild (from viruses the original commenters claim, this article is about a trojan, which also is a lot more prevalent on windows than on the Mac.)
But don't let these facts get in the way-- remember, the point of this thread specifically, and a big amount of the draw of Hacker News, is that you can bash Apple and get up voted by other Apple haters. Facts are not relevant.
If you had answered my question you would be able to pick out at least one thing that Microsoft had done that Apple had not.
You said: Microsoft did their job years ago, now Apple has to follow.
This is simply not supported by the facts.
