Well, I, too, am among the few who don't use a smartphone. I actually do have one that I bought second-hand, but I prefer my little pocket phone which does not even have a camera.
But, as was earlier stated, it looks like if I ever even want to travel on an airline I will be forced to use a smartphone. The one I have is old and rickety, so a shiny new one it'll have to be. So far, I'm still managing very well with my little cell phone on which I get probably fewer than half a dozen calls a week. Any online business--serious or nonsense--is done at my computer, and, having done so for decades now, I'm quite comfortable operating one. I know that I will have to take the plunge one day, though.
