I have had my Smart Phone for approximately five years. It was a gift from The Ravishing Mrs. TB, something to get me "plugged in" to real world from the previous Flip Phone.
The Modern Smart Phone is a miracle of replacement technology. Without using any of its communication features it has successfully replaced the watch (pocket and wrist), the calculator, the music storage and playing device (a.k.a. The Walkman), the physical notepad, the camera, and the pocket flashlight (by far the most useful feature). It makes all kinds of communication, written and verbal, possible. It allows one to check in on one's children in a way my parent's generation must have only dreamed of. Add to that its functionality as a entertainment and knowledge center - literally, the world is right at your fingertips - and you have essentially poured all of the human experience into something you can hold in your hands.
And yet I am considering it to be more and more of a paperweight.
The Smart Phone has changed our behavior. We are now a people that spend most of our time with our heads downward facing our screens, a pack of hollow eyed zombies stumbling over curbs and into walls as we walk. We interact with the phone - through selfies, through conversation, through laughing at what we see - as much or more so than with actual people at this point. The world slowly becomes invisible except as viewed through a screen.
It has also changed how we respond to each other. In days past, responses were largely a result of personal interaction. Now, the omnipresence of the Smart Phone and the power of text make everything a "right now" response. If you are not responding "right now", something is obviously wrong or you are simply not paying attention. The sender has now become the most important person in the room - by not being in the room.
But for me, the question has become very much about how I actually use the phone - as a communication device. Frankly, I really do not any more. The handful of calls I make or get outside of family are either recruiters or people trying to sell me something. My texts, which originally seemed to replace the calls, are simply an extension of this as well.
In other words, I scarcely use my communication device to communicate anymore.
Will I ditch the phone immediately? Of course not. It works, it is paid for, and it does have that rather useful flashlight. But I am reaching zero initiative on getting a replacement model if and when this one perishes. I can do a lot of what the phone does on my computer. I can get an actual phone for people who actually want to call me (or text, I suppose).
I will sure miss the flashlight though.
