You've got shops which make Mac apps, Windows apps, and both, and it's three fairly different cultures. The "both" shops are mostly large and well established, Macs have a lot of indie devs, and Windows has a deep culture of B2B apps that is chugging along just fine. Not to mention PC games, which are certainly desktop apps, but I consider them in their own category and figure games aren't what you meant either.
