If you don't find value in smartphones I can respect that
You'd have to pry my own from my cold, dead hands. I have a map of the entire world (mostly) in my pocket! That in itself I find invaluable. I use Google Maps all the time. To find places and to navigate to them. On foot, public transit, and car. Here and in other countries.
Sure, I used to manage before Maps was a thing but do I ever want to go back? Nope.
That is one killer feature for me
And yeah I definitely see how life changed for the worse because of them. I actively moderate my own behavior.
