The application model generated from Storyboard Designer doesn't require compilation and is target environment agnostic. This makes it straightforward to generate applications that execute in a variety of different environments, such as an application that can work both on an embedded device (for example a wall thermostat) and in a mobile context.
Another advantage of being hardware and operating system agnostic is that elements of the user interface can be used as part of a product's hardware evaluation process. It takes only minutes to create a rich animated application when working with the Photoshop import functionality. The application can be immediately evaluated on any one of the over forty different platform configurations spanning more than a dozen operating systems and popular rendering technologies.
