You seem to assume that the demand (market) is static. My impression is that it is shifting with a growing demand for bigger screens and thus phablets. People have now experienced the problem of browsing the web with 4" screens. Regarding the screen size problem, my vision is that the communication functionality (I/O) will be taken over by dedicated devices using bluetooth. Such devices could be a watch, light and invisible ear plug, microphone and camera. The one big block of material doing everything as we have today is just a step in evolution. There is so much open space left to explore and develop...The demand is evolving, and fast.
