I've never lived without a phone, so I can't report any change as a result of this achievement. I was also one of the very early users of mobile phones - at that time still in a box with a handset on a cord ;-))
By the time my children arrived, our lives would no longer have worked without mobile phones. If there's only one bus a day and the child misses it, it's out in the sticks and has to be picked up...
I don't deny the benefits and the fact that how much easier our lives have become because of technology. I have seen the life without phones (but as a kid), now I can't imagine a day without one.
Having said that, every great invention comes with its own set of repercussions. I'm mostly worried about lack of time, creativity and concentration.
