I agree that for phone apps, this works well, but disagree that it ports well to tablets. I mean, it is okay for tablets, perhaps better than some other approaches, but I really believe that a different primary navigation method is needed for apps. Primary nab should be within thumbs reach. This implies that most of the important navigation items are within a couple of inches of the bottom corners of the screen. Much of what is currently being used requires a one handed approach to the tablet which slows the user down unnecessarily. I'd really like to see more aggressive approaches to tablet UI than we're currently getting from iOS devs.
