Apple get's pwned

The only thing shocking about this story is the fact that Steve Jobs didn't come crashing down through the ceiling on a helicopter repelling line, snatch the compromised machine and use one of those Men In Black flashy things on all of the attendees in the room.

To sum up (because there is too much to 'splain) what happened, a fully patched Mac running a 64 bit version of the OS was hacked in 5 seconds by having the Mac visit a compromised website. The hacker was able to launch the calculator app and write a file to the desktop. This hack took place at the Pwn2Own hacker competition this year.
To be fair, it took the hackers 2 weeks to write the exploit from scratch AND later in the day an Windows 7 (32bit) machine running IE 8 was hacked exposing 3 vulnerabilities. However, this little exercise proves my point that Mac's may have a little more going for them in the security department then a standard Windows installation, but they are not hack proof. By far the largest factor in Apple's apparent resistance to hacking (and all the other stuff that goes along with it) is market share. Plain and simple. Apple has something around 4.5% of the total computer market. That's a pretty small percentage of the computer using population. Why hack that when you can hack Windows machines and get over 80%? As Apple's market share grows, so will the number of exploits and hacks.
