I think I got my first smartphone when I was 23, I never use them for anything other than calling, youtube, and basic web browsing
My typing speed on a phone is something like 15 wpm, on a computer keyboard it's 110 wpm
The idea of using a smartphone for anything pleasurable (other than youtube) is totally foreign to me
I remember in high-school you'd basically know who the rich or fiscally irresponsible girls were because their parents bought them brand new razors/blackberrys/etc. Everyone else (like me) either had tracphones or nothing! That heuristic isn't as useful today.
