Your claim that " MacBook Air pwned and owned in less than two minutes" is totally false and a complete misrepresentation.

1) Miller says he worked for a week trying to come up with the exploit.
2) On the first day, he was totally unable to come up with anything that could get into the Mac.
3) On the second day, active participation on the part of a user (automated) was required. It's the old "click here for free porn" exploit, following which a user had to choose to get the porn, choose to download the exploit, and choose to install it.

Let's do some math. Recently, Sophos predicted that there will be 1,000,000 viruses for Windows computers by the end of this year (http://www.pcworld.com/article/id,144181-pg,1/article.html ). Currently, there are NO pieces of malware for the Mac in the wild. If malware writers came up with 1,000 new viruses and other malware for the Mac every week, it would take twenty years for the Mac to match the number of viruses for Windows.

Which do YOU think is more secure?

Well if this is so - where are the compromised Macs?

I'm getting tired of these inane comments for many reasons:
1. It's just not true. There have been platforms with far lower installed base than Mac OS which had viruses (BeOS or AmigaOS, for example). Or, more relevantly, there were Vista-native viruses before Vista passed Mac OS X in installed base. If it was all about market share as this author alleges, that would not be possible.
2. Who cares what the reason is? Today, there are tens of millions of zombie Windows computers and no zombie Macs. Does it really matter WHY that is true? If you want a safe computer today, it's a Mac. It's possible that in 30 years, Apple would pass Microsoft in market share. It's also possible that Apple would then have more viruses than Windows. But why would that influence your decision on which computer to buy TODAY?

This is just loose talk by someone who either doesn't know better or has a reason to spread falsehood. The Mac isn't impervious but is certainly much more secure than Windows is. In fact all unix OSes are similarly more secure, for a variety of reasons.

The mac is not more "secure" really 1 million viruses? They are likely counting all versions of windows and all the variations of the same viruses. No operating system is safe, given the the source code any system can be exploited. Mac users more then window users at the moment due to the sheer fact of misplaced trust in security, a mac user would be more willing to click a link or install something thinking they are immune.
