Some people like tech free existence, and by all means pursue it. I admire such people. I need my smartphone to call my folks living half way across the world via hangouts, share pics, look up recipes, post in online forums, read news, track expenses, flash light, bar code scanner, travel apps esp on work trips, listen to music, watch youtube series, jot down thoughts, play few games, hail uber rides, borrow audio books from library, buy train tickets etc. I could do all this without a smartphone but having one helps me to be far less stressed.
