thats true, to say macs DONT get viruses is not true. i say DONT in the sense that they aren't as heavily exploited as windows, SQL, etc.
i still stand by my notion that there is nothing to be gained from hacking broke mac users.
case: a hacker wants to hack for financial gain. does he:
a. exploit a vulnerability on a single mac machine on an unsecured network
b. exploit a vulnerability on a SQL database containing 1000's of credit card numbers
