BTW, most of this interface was possible because of the external keyboard and even though it used the traditional UI elements like top text menu items with drop downs and modal dialogues (basically a windowing desktop system). The interface was very well optimized for keyboard shortcuts and navigation. With our current high resolution displays we use our fat round fingers as pointers and information density suffers. That seems to be the reason they're not used. (Windows mobile used stylus as pointer to solve this problem and keep the common windowing desktop paradigm).
