And because of that it was not accessible to everybody. But today everybody has a mobile phone. Many people, primarily younger people cannot live without their iPhone.

Because the phone is so easy to carry around, it got a new purpose. Then the mobile phone was invented first time, the phone itself were heavy as a brick and could only hold battery for about 20 minutes.
