This story has come under attack on a bunch of Mac sites.
The writer is an ignoramus or in the pay of Microsoft.
Please explain how the two are mutually exclusive.
The most important part of the article:
QUOTE
Hoopes said Mac OS X is based on the UNIX operating system, which was developed by Bell Labs in the 1960's and at the University of California, Berkeley, through the 1970s. Variants of Unix power most of the servers on the Internet and the system has a reputation for security.
Although experts give Microsoft credit for greatly improving the security of its Windows operating system over the last few years, most still say Apple has the Seattle software giant beat.
"The Mac OS X has a higher security profile," said Ray Wagner, a vice president at Gartner, a technology research firm. "It's not generating anywhere near the same rate of problems, even on a per capita basis."
What I fail to hear is that anyone who manages to break into the Mac OS with a virus would get not only fame but a small but supposedly wealthy group of targets. After all, if Macs are so expensive then their purchasers would present a more lucrative victim than the average PC user. On the other hand, PC users are probably less intelligent so they would be easier to dupe... 
Yeah, OK, I used all the typical stereotypes, but gee wiz didn't the author of the article? 
Oh, the last line.. "Apple did not comment on this story."
No, they were too busy laughing their ***es off!

Microsoft says virus-creators are starting to train their sights on other platforms.
"As we've made improvements to the security of Microsoft software and services, we've seen cyber criminals shift their focus to other platforms and applications," said Stephen Toulouse, Microsoft's security program manager.
Apple did not comment on this story.
I think this kind of says it all and as kbear says. it's a poorly written article.
