For a start, it’s not just your phone. It’s your newspaper, alarm clock and camera. It’s your TV and department store. And for lots of us, it’s our gaming console, heart monitor, means of assessing how far we’ve walked and what we’ve eaten every day. It may well be the irst thing we check in the morning – maybe even before looking at the person sleeping next to us – and the last thing we look at at night. We’re so intimate with it, we’ll even take it to the loo.
