People keep talking about lack of viruses and spyware in OSX, but if we were to be honest OSX has its fair share of spyware, browser vulnerabilities, straight bang on security holes and other malware. Of course the problems are marginalized and attract less attention compared to Windows, but that is related to Macs market share, not the fact it's ultra secure (and of course it is not, if anything it is the most vulnerable OS of all BSD based systems). It is even more so, considering a lot of its internals and programs are based on often buggy open source bits which can be patched quickly on linux or any other form of unix but are often neglected on OSX because of the way Apple rolls out the patches.
Macs can win over a lot of users, and I'm glad to see OSX fanbase grow, but let's not be silly here and let's not try to imply OSX is in any way unbreakable or unhackable system, because the more it is repeated the more hackers will make a point of proving otherwise and in light of the fact most OSX users don't know first thing about BSD consequences might be severe. In many ways it is like sticking "The most secure home in the hood" on your front door . You don't want windows like attention, so let's enjoy this "security" quietly, shall we?
Another thing is that usurped "anything just works on mac" business. Anything works on mac because you are not trying to stick incompatible hardware inside. no one buys Soundblaster cards for their Mac Mini or try to shove some chinese five quid worth of TV card up its USB port. If you try you will discover not everything works on macs. In fact, most probably 95% of hardware as we know it doesn't. If people with Vista followed "Vista Ready" stickers rather than try and recycle their old hardware they would probably be singing prises too.
All the above of course doesn't make OSX less enjoyable in any way. All I'm saying is - if you want to glorify it - glorify it for right reasons, its strenghts, not its hype.
