I used to be at the bleeding edge of tech and I refuse to move to a smartphone simply because of the distraction it causes. I have a real problem dealing with distractions as it is and adding such a device would make my life much harder. Tech is here to serve us, not the other way around and in the end what matters is whether or not a given piece of technology improves your life so much that the downsides are more than balanced out. For smartphones in my life that would be a net negative. Of course for others that equation works out differently.
