Iain Banks, in 1988 (!), correctly predicting the problems of suspense writing in the age of smart phones:
Stories set in the Culture in which Things Went Wrong tended to start with humans losing or forgetting or deliberately leaving behind their terminal. It was a conventional opening, the equivalent of straying off the path in the wild woods in one age, or a car breaking down at night on a lonely road in another. A terminal, in the shape of a ring, button, bracelet or pen or whatever, was your link with everybody and everything else in the Culture. With a terminal, you were never more than a question or a shout away from almost anything you wanted to know, or almost any help you could possibly need.
