Crying Wolf or a Good Reminder About Malware?

"Oh, the rationalizations people come up with to explain away what they don't want to hear. Last week, when I wrote Coming soon to a Mac near you: serious malware, I expected to get an earful from Mac partisans telling me how wrong I was. They didn't disappoint."

His article at ZDNet was a heads up of sorts, letting the OS X users know not to get too relaxed about malware, and citing several sources as to why he believes it is coming. Of course he knew he would be getting replies from the OS X "zealots" (or should I say "Mac Faithful") about this article, so he responds here point by point. Bottom line is, to me, you have to be careful regardless of the platform you are using. Malware can come in many forms so watch what you are doing on the Internet. It seems that Gruber doesn't put much faith in any of this malware business though, at least according to his post here. What are your thoughts? Is Ed Bott really crying wolf as Gruber suggests?
