I should have mentioned that my apps are iPhone apps. You're correct in saying that his advice makes more sense for desktop apps. However, he doesn't say that and the only store he explicitly mentions in the blog post is the iPhone/iPad app store. That said, I think that the website will probably be more important for a $99 mobile app than it is for a $0.99 mobile app.
