The iPhone platform elegantly solves the design problem of small screens by greatly intensifying the information resolution of each displayed page. Small screens, as on traditional cell phones, show very little information per screen, which in turn leads to deep hierarchies of stacked-up thin information--too often leaving users with "Where am I?" puzzles. Better to have users looking over material adjacent in space rather than stacked in time.

As such, Trevithick said data portability would help bring about an Internet of the future where you don’t have to repeat yourself, because your data would exist in cloud that’s accessible whenever and wherever you go online.
