This hands approach, especially with something as complicated as the iPhone, really does the job to tear down the walls of just sitting there and plugging away at code and "Sort Of" getting it and really opens up more intuitive "I Get It!!!" leaps. This book series is not only good for beginners but also intermediates that need that last bit of hand holding so that they are ready to stride out on there own and become an expert... an expert on there own... Which means practice, practice practice. But perhaps fear of Failure kept the intermediate programmer from picking up there standard and take it on. This will help eliminate that fear.
