And as far as those "default" Mac settings:

Sorry, no cigar. These "exploits" were LAN only and required that a hostile server exists on the LAN. This is so unlikely a scenario that it is almost beyond the realms of possibility. The exploit was easily fixed by merely turning one default setting from "on" to "off." It did not even require a patch.

Later release CDs of OSX shipped with the default "off."

From "not vulnerable" to "well, it is vulnerable but..." The fact remains that you simply don't have enough market share to justify virus writers targeting your little OS.
