speaking of linux hacking... my company had a bunch of bsd servers get hacked a couple weeks ago. Granted they weren't properly firewalled and I doubt they had the latest updates... But people can and do hack non-windows systems. That's about the 4th time I've seen one or more linux or bsd servers get hacked.

There are over 1,600 known Security Vulnerabilities in OS-X. (Compared to about 180 in Windows 7 and 450 in Windows XP.)

Apples OS's have terrible security and known critical vulnerabilties frequently go unpatched for years.

In fact the only thing with worse security than OS-X is Linux.
