For example, I recently visited London and travelled on the tube while I was there. Apart from the people asleep, almost everybody else was on their phones, and because of the nature of the tube, it is difficult not to see exactly what they are all doing. Of course, being underground it is difficult to get any signal, which rules out texting or using the internet, but there is still plenty you can use your phones for. People were playing games, reading articles and listening to music, and I am sure that as soon as they emerged from the train station they would start texting or calling or checking their emails. There is a constant connection to everyone in the world, as long as you have a mobile phone in your hand.
