>> more exploits being found for OSX than Linux and windows
I don't believe that for Linux, and I certainly don't believe that for Windows.
Face it guys, OS X is built on a BSD userland with the same OpenSSH you all know and love. It uses the same owner/group/others file permissions. It ships with an excellent firewall, and no open ports by default.
IMO, it's as safe as Linux. The smart users will only ever see trojans and home-dir-deleting "viruses", and the dumb ones that type their password will get owned.
The probability of hitting a Mac, and then having the user enter their password into a random unexpected popup is too low for Macs to be a viable target.
