Nice answer. Wrong question.
I was asking how you or I getting a Mac reduces the headache of unpatched-windoze boxes out there that drag down the net with DOS attacks, spam, etc.
You're correct that Microsoft's program here will do nothing but encourage more Chinese pirate machines to stay unpatched. Buying Macs doesn't fix that.
It doesn't, you are correct. What would help is if we can convince a few million people to make the switch. :-)
