I also carry one of those Kindle tablets in case I need to go on-line on the road or want to read on a plane. It gives me a much better picture than a silly smartphones. About the only real use I'd have for a Smartphone is to take pictures of checks to deposit. That would be handy but not enough to justify a monthly fee as long as banks still accept deposits at ATM machines.
I upgraded to a ‘slide phone’ with a keyboard a few years ago- I prefer texting to calling. But I may go back to a flip. And yes, a cheap Kindle Fire for keeping up with FR on the road.
