It's been a handful of days since I turned off my smartphone and I've already noticed some changes. My long dormant keypad typing skills are coming back which is fun. My anxiety about not having a smartphone is starting to fade. I'm really enjoying my single purpose devices (nex-5, xteink4, gbc, Voyager 2). Auto complete typing made me nervous. Having a notification light on my phone is a game changer. We'll see how it goes but I don't think I'm going back.
