Neal Stephenson Explains What's Wrong with Mobile Phones
What's intriguing is that Stephenson is saying mobiles suck not just because of their interfaces, but because of how people act when they use mobiles. Of course, how people act with cell phones has everything to do with the interface. You have to stick them against your face, or put some weirdass Cyberman-looking thing in your ear. So your body language, when you're on a mobile, makes you immediately seem rude to anyone around you.
Plus, most people still use audible ringers (as opposed to vibration), so it is essentially impossible to have a mobile without inviting a noisy, irritating interruption. What that means is your mobile doesn't just interrupt your train of thought or conversation -- it interrupts everyone's within earshot. So the mobile as we know it is perhaps one of the worst attention-shattering devices imaginable.
