New phones, such as the iPhone, have made our daily lives much less laborious and give us more free time. Jobs that required lots of energy and time can now be done at the touch of a button. For example, if we wanted to communicate with one another in the past, we had to write a letter, take it to the post office and then wait for it to be delivered, whereas these days we can simply tap the email icon on our touch screen and send a message in seconds.
