Honestly, for me, it’s the one-two-three punch of easy notes taken anywhere + podcasts + camera.

• notes : before smartphones I carried a notebook in my pocket. And sometimes I still do; writing longhand is still pleasant for me, and being able to sketch and doodle with my notes is still clunky with a touchscreen, amazingly. But the experience of losing my notebook, or not having the right one with me when I need it, is disproportionately frustrating to me.

• podcasts : this is one of the few ways my ADHD brain truly focuses. Listening to a podcast while walking, biking, running, driving, doing dishes, cleaning a room, mowing the lawn, etc. is almost foolproof in getting me to pay attention to the content. I have to be in the right mood to read, and videos are background noise to me after having the Discovery Channel or Scifi Channel on 24/7 in my apartment in college. Before smartphones I had a trusty RCA Lyra that went everywhere with me; and while the form factor and experience were fantastic, I now have a backlog of over 800 podcast episodes that would not fit on that device’s 512MB internal storage. (Also, I just got a pair of noise canceling earbuds, and I have to admit I really like them)

• camera : I’ve chosen my last four smartphones based on the camera quality. I’ve got kids, and being able to take adorable pictures of them at the drop of a hat is very useful to me. I don’t need all the computational nonsense, but I do need it to be good enough and ever-present. Before smartphones, I would occasionally bring a digital camera around with me, but I can’t afford one that would give me the quality I want, and it wouldn’t fit in my pocket anyway.

Messaging, fitness tracking, and work stuff is also easier, though not in a way that I don’t think I could backfill with other things if needed.

Nostalgia aside, the experience of these big three use cases is indisputably better with a smartphone than it was in 2005. Could I live without them? Yes! Absolutely. But I’d prefer not to, and since I shook my social media addiction I don’t really feel the need to.
