In short words what he is saying:

Symantec tells us we are going to run into trouble.
Because we are so naive.
Caught absolutely unaware.

Because our OS is not as immune as we naive Mac-worshippers think.

And there weren't any reallly threatening viruses (viriiiiusi) up to now because Apple is the absolute niche product (that could never even cause software developers like Microsoft or Adobe or Maya tech. or the other hundreds to even port software to the OS X platform. Which soooo small a company with negligible market share could....). And who would like to develop a virus for OS X or for Un*x or Solaris or so. (WHISPER:He just would be the hero. Finally a virus for those "safe" systems! Unix exists since approx.1969-1972.)

It sounds so incredibly mature and grown-up (I'm fourty, btw...) and wise to say things like "this influenza epidemy will finally strike us really hard" or "Apple will die next year" or "We will have a second legislative period under this one".....
But it is not.

I prefer the facts. We HAVE a nice system. Quite honest to its user. Quite virus safe. If this changes, let's see.

What is far more interesting than the OS is the gros of the users.
How bug tolerant are Mac users? How tired of all the futile attempts to keep the system clean (virus, dialers, dll's, undeletable windows always popping up during boot) are we? Where could viri find a nest? Do we just double click every mail?
In other words: How strong is the effect of pre-selection to become a Mac user?
Let's not compare the OSes but the collective of users such an OS gerenates.....

Only one issue I need an answer urgently:

Why do I keep feeding them, even in this posting......
