majazac...windows always has security issues. but you have to disable the windows firewall. or change the security scale, it's in your control panel.
myscrnnm II, give us reason to switch to tiger OS. I would say that's a waste of money and time. Flexibility, options, and using windows and open source software (sometimes) are unavailable options to mac users. Web development is restricted and programming as well. You have to BUY extra software. and BUY special video cards that really suck and you have to pay premium for them.
