I read the article, but I'm not sure I understand exactly what "makes OS X king of security"? ASLR, privilege separation, and encryption aren't exactly new things (at least in Linux/GCC/SELinux/AppArmor).
The title almost sounds like SHA256 was broken while Lion was written and everyone else is vulnerable.
Not a lot of companies can sell something like ASLR and basic application restrictions this well.
In some other communities it's not well-understood that it's not just about feature checkboxing. It's about shaping features in such a manner that they are trivial to use.
I do realize that to Apple-dislikers I am well under the spell of the reality distortion field ;).
It is just that people who use a computer for nothing more than generic stuff like browsing / word-processing feel this need to defend their OS choice (while potentially using the exact applications which they used on their previous platform) with articles like this. Soon ASLR will become "the killer feature" and Apple will be declared the first to invent it and the Linux/Win fanboys will be pissed.
This of course is the circle of life in the tech industry. One just needs to stand at a distance and enjoy.
The article is typical El Reg, but the researchers aren't uncritically gushing.
Remember when XP came out? (oh god, did I just age myself) That was also chock-a-block full of press release style articles in the news about how impenetrable it was.
Mac is "king of security" only in the sense that it covers about 10% of the market and people aren't writing viruses for it.
Oh well... really "punchy" headline though got me to click.
