I can hear you aren't very fond of Mac. I don't understand why. About the security thing. I read about this contest, where a Mac server was set up. You could win 10k dollars if you were able to in any way break into it. A month was set off to do it, and tons of people tried. After a month, no one had even gotten close. So they raised the sum of money, and people tried harder. No one got in. Btw it had no firewall or any other kind of protection software.
