It is definitely not the ultimate form factor. We know that people will sacrifice power and medium-term convenience for portability and always on connections that work in the real world, so if we maximize those: I am thinking of an Apple glass with AR holographic display that is hooked up to a controller you can keep in your pocket for when you can't use Siri as much closer to the ultimate interface. You want access to all the information, but at the same time have your hands free and the privacy required when you are out and about. Eventually there will be a direct neural interface to your pocket terminal with POTS compatibility and you won't need either voice Siri on a hand based input.
