I still have my Newton and my HP-48SX. Yeah, the Newton was clearly ahead of its time. Maybe the main thing that "made" the iPhone was connectivity (and ofcourse having the "Internet" to connect to) - neither were really there for the Newton (or other PDAs for that matter). It's those intersections in technology Internet/Celluar network/Hardware/Software where things take off. An expensive cool PDA without the rest of it is just that. The iPhone was a little bit cheaper (again driven by hardware technologies maturing).
