It amazes me that so many "Marketers" of products would overlook at least 1/2 (if not more) of their potential market. If you look at the download stats for PC VS MAC files they are almost 2 to 1. Due to the iMac I've noticed more & more new MAC users who are asking questions regarding file conversion questions on various sites. Platform wars are a dead end, we can learn just as much regarding program techniques used on any system. It's to our collective advantage that publishers are aware of that.
