I know what you're saying, but in terms of shifting software I had this particular quote in mind:
I'd err on the side of caution and take him at his word -- just because there is less Mac software it doesn't follow that you can shovel shite at them.
In my experience of writing for Mac and PC mags over the past seven years or so, it's clear that Mac users in general are much, much more likely to pay for shareware, and that Windows users are more likely to hunt around for cracks. Also, Mac shareware—unlike commercial software—is generally of a higher quality than Windows stuff.
