Why is this important?
Many applications embed HTML to provide a richer and always up to date experience for consumers. For example, the developer of a restaurant guide app might want to include a live map showing the locations of the list of restaurants the user is choosing from. If you write an app on iOS, common actions like panning and zooming the map will run twice as slow in an app compared with Safari.

With Metro style apps, it’s easy to integrate many existing Web services seamlessly into your app. It’s also possible to build new services for your app that let you deliver dynamic HTML content without having to update your application.
