The advantage of an app store app over a web app seems rather thin to me. The marketing required to get an app high enough in an app store for a user to notice seems no different from the marketing required to get a web app noticed. However, with a web app only customers get to decide whether or not they use it. There is no corporate intermediary that would, for whatever reason, decide to not let customers choose your app. And, as this story illustrates, the risk of being abruptly booted out of an app store without knowing why is real.
