We’ve taken Super Checkout a long way since the beginning of this book. Testing has gone well, the feedback from the users is coming in, and they overwhelmingly want an iPad version of this application. So what do we do now? Do we separate out some of the common code and build two completely different applications, or do we build a universal binary? That decision depends on your goals for the application; it isn’t dictated by technology. It is generally a business decision, because multiple applications can mean more revenue. A universal application, on the other hand, is generally better for the end user, who can purchase one application that will run on the iPhone, iPod Touch, and iPad.
