Oh yeah, and you "get a mac" people, same goes for you.
There is nothing 'magical' about OSX... its just that the only real 'market' that MACs own is the graphic production and print industries.
As percentage of MACs grow in the 'home user' market you can expect more and more 'trojans' and 'viri' to increase proportionally.
I dunno... not all operating systems' security models are created equal. Just because someone wants to write a trojan or virus doesn't mean that it will be just as easy on OS X as on Windows. In fact, from what I understand, the opposite is true.
