Has anyone driven a truck thru these gaping holes? Anyone? Beuller? When OSX is suffering from a deluge of viruses from all these supposed gaping holes in it's Architecture, please come back and let us know. Because while every operating system has vulnerabilities, only Microsoft was kind enough to make those vulnerabilities accessible by system wide scripting mechanisms that allowed millions of computer users the world over be the subject of attacks from the hundreds of thousands of pieces of malware constantly fighting to infect Windows PCs. The count (for those who think a security vulnerability makes Apple's points about viruses invalid) is about one hundred thousand to 0. This is being very generous. So, yes, as a matter of fact, there are no viruses for Mac OS X. Not virtually none, not almost none. None.
