i - diots. And I don't mean it in a derogatory sense.
People buy in to macs because:
The hardware looks better. (oh yes, it does)
The thing works almost as well as advertised (and yes, it does)
The advertisement promises a "no cares" attitude (oh oh - this can be a spot of bother)
The thing is in OSX land there be a few snakes. These are dangerous you see, because the snakes are transparent.
Because the system is not transparent.
The mindset is: "it just works"
Yes it does, it is quite nicely engineered (and it doesn't have to cope with an almost infinite number of uncontrollable configuration permutations, 20 years of backlog/legacy software).
And it did not have to deal with being popular, in the numbers kind of way.
Until now.
So, the malware (scare or the real thing) was something the "lowly PC people" had to deal with, and not the apple crowd - they thought they were too exclusive, too untouchable, an idea they readily bought into.
in the end an OS is just an OS. Anything can be hacked, if it's worth the effort.
Through the many advances and the subsequent layers in UI/UX majickery the computer may _feel_ like an appliance, but it is not an appliance. It can still bite you.
Learn about the dipstick in your car. Learn about malware in the wild outback that is the interwebs.
The moral of my story is: Don't be a blithering idiot.
