As I watched mobile phones become tinier from 1996-2006, I wondered what the endpoint would be. Some were so comically small as to be useless to anybody over the age of 40. Would we eventually be depositing them directly into our ears?, we wondered. And then along came the iPhone. It’s on the larger end of phones on the market today. But it does way more than most other phones. And thus came this realization: Technologies will shrink indefinitely, but products will adopt more technologies to maintain the smallest practical size. In two years, when the technological components of the iPhone would allow it to be half of its current size, it will come to incorporate a projector, video camera, and other delights that only Jonathan Ives can predict.
