A History of Cell Phones,

The original cell phones made one single break with the interface of the wired phones that had come before: The user dialed, then pressed Send, instead of dialing “live” as had been done historically. That’s it. Added later were such niceties as keyboards for message and email construction, borrowed whole, again, from the wired world. (Even the Send button was borrowed from earlier Radio-Telephone technology.)
Occasionally, bits and pieces of interface innovation have found their way into subsequent cell phones, but no one has ever revisited Bell Lab’s pushbutton phone design from the 1950s with its upside-down adding machine keyboard (with the exception of Smart Phones, based on the 1870s typewriter keyboard).
IPhone is revolutionary, not a big surprise coming from Steve Jobs. He knows how to gather a tiny team of brilliant young minds and work them half to death until they innovate beyond any reasonable expectations. He has the common sense to know what will ultimately find favor. And he has the hardened-steel man parts to take a chance and roll with it. What’s a pity is that so few others in this industry share those triple strengths.
