Wow! A month of Apple bugs and roughly 30 years (and counting) of M-Soft bugs. Apple has a long way to go to be as good at security flaws as M-Soft, but give them credit they're trying.
Apple has been flying under the hackers radar. Just like Linux once did. Their smugness has led hackers to show they aren't perfect either. We all know Windows isn't perfect, but the reason they have the most exploits found is because they have the biggest footprint and hackers won't waste time trying to attack a handful of machines.
If you're saying no exploits makes an OS secure, then you will want to buy the one I wrote as it has yet to be exploited. Of course I'm the only one that has ever used it, but it must be secure since no one has ever hacked it. /sarcasm
