sensitive question
Dear stchman,
You can consider Apple to be a religion like Microsoft is also an religion. Now consider yourself as an atheist to be entering a Church "Can we just throw Jesus out and bring Allah in the door!", how would you expect this conversation to end?
Now since some time, the Apple Macs accept the other competitors software (and malware btw), however they do not have a native installer for just windows. What you could do however, is give windows as the primary startup option (so that you do not need to hold the option key to enter the partition). This should make it very comfortable to work on Windows.
Very good luck with downloading all those virusses...
