Portable (video)calling devices were the integral part of science fiction & cyberpunk for 40 years at least. The earliest mention of smartwatch-like handset I’d managed to dig up was in The Stars My Destination by Alfred Bester, 1956.

«Sorry, Presteign. Where's the circus now, Fourmyle?»

«I don't know,» Foyle said. «Just a moment.»

A crowd gathered, grinning in anticipation of the latest Fourmyle folly. He took out a platinum watch and snapped open the case. The face of a valet appeared on the dial.

«Ahhh. . . whatever your name is. . . Where are we staying just now?» The answer was tiny and tinny. «You gave orders to make New York your permanent residence, Fourmyle.»

«Oh? Did I? And?»

«We bought St. Patrick's Cathedral, Fourmyle.»

«And where is that?»

«Old St. Patrick's, Fourmyle. On Fifth Avenue and what was formerly 5oth Street. We've pitched the camp inside.»

«Thank you.» Fourmyle closed the platinum Hunter.

So it was only a matter of time for technology to finally reach such level of integration. Nothing so weird really. We’ve just grown up into future they wrote.
