“If there is a billion-dollar gamble underlying Apple’s iPhone, it lies in what this smart cellphone does not have: a mechanical keyboard. As the clearest expression yet of the Apple chief executive’s spartan design aesthetic, the iPhone sports only one mechanical button, to return a user to the home screen. It echoes Steven P. Jobs’s decree two decades ago that a computer mouse should have a single button. (Most computer mice these days have two.) His argument was that one button ensured that it would be impossible to push the wrong button.”
