U P D A T E
It looks like Bill Thompson has been flamed on his article which I think is crazy - He is a Mac user speaking his mind - he has responded to the comments (link) and support his view:
In this article, I was speaking to an audience of Mac users of all skill levels, some of whom know nothing about computers. They need to understand that security matters to them just as much as it matters to Windows users.
I hope I achieved that goal, even if I did upset a lot of people who seem to feel that anything but fawning admiration for Apple is an act of betrayal by an apostate.
