Developing and Testing on a platform that is representative of your target market, is an absolute must and fundamental best practice.
This is where we disagree. If you feel more productive developing on the Mac or Linux, then why would you use a platform where you are less productive? It just doesn't make sense. You just need to test it on Windows.
As an example, Google developers require a special permission to use Windows (as they consider it less secure).

Why, the main reason is because you can identify issues at the "start" of the product development life cycle rather than later on. It's just best practice. I understand that Dev's feel more productive on certain platforms, however a percentage of the Dev's need to take some pain, so that the customer doesn't.
