The document discusses different models for publishing content on the iPad: the store front model, browser based model, and app based model. It argues that the app based model through YUDU's app is the best approach, as it allows for simple purchases through the App Store, easy searching and browsing of titles, and focuses users on making purchases. YUDU has developed the first self-publishing iPad app to provide this experience. Their model also manages the app creation and submission process, providing publishers an easy way to reach iPad users without the headaches of app development or management.
