It's a dream, a bad dream. I'm standing on a street corner, it's late, it's dark, I know my location but I don't know where I am. There are figures in the shadows. I am not comfortable. I decide to call a cab and I reach into my pocket, pick up my phone, the latest model from a leading manufacturer, click to wake it up - but it's dead. And it's only six hours since I unplugged it from the USB cable that it spends most of its life attached to in the office. It might still be a cellphone, but it's hardly mobile, says Pete Jackson.
