Bearing in mind that PC's are ubiquitous and will always be, I'm not sure how this post helps anything.
Furthermore, claiming that Apple is immune from the exact same sort of attack is nothing short of misplaced hubris.

IBM Selectric typewriters used to be ubiquitous too. Nothing lasts forever. Microsoft will fall from its current position sooner or later.

The main reason that this is not so is due to Microsoft's poor implementation of Administrator privileges. There are many Windows programs that still don't run except in Administrator mode, and thus there are far too many grannies, kids, office drones, and other assorted lusers running Windows as administrators. This allows rooting of your PC box from a website or an e-mail attachment without any further intervention by the luser.
In OS X and other Unix systems, by contrast, the bright line dividing super-users and regular users has been well established for decades. There are no OS X application programs that require Administrator/super-user rights, and any mucking with the system requires explicit super-user validation. A malware payload of the type discussed here would bring up a dialog box requring the user to explicitly give a super-user's name and password before it could proceed.
