I have been saying for a few years that as society starts to realize how destructive smartphones have been to our minds, there will be a resurgence / renaissance of "single use devices" and even print media and paper.

A music player that just plays music, a camera that's just a camera, newsletters that are printed out and actually come to your house.

I'm probably wrong and it's just wishful thinking, but watch for this stuff become "cool" at some point. It will be seen as way to differentiate yourself and be unique, that's when it may catch on.
