Stand at a platform at a train station and look at the crowd. Everyone who is not looking down is currently talking to a person, either on their phone, or there at the station. Everyone else is looking down, fiddling with their phones. Before the smartphone, the only people who did this was the rare book-reader. The smartphone would have come to us eventually, but the iphone hastened it's arrival by more than a few years.
