Warren Ellis, How To See The Future:
The most basic mobile phone is in fact a communications devices that shames all of science fiction, all the wrist radios and handheld communicators. Captain Kirk had to tune his fucking communicator and it couldn’t text or take a photo that he could stick a nice Polaroid filter on. Science fiction didn’t see the mobile phone coming. It certainly didn’t see the glowing glass windows many of us carry now, where we make amazing things happen by pointing at it with our fingers like goddamn wizards.
