Obviously, OP can give a better answer as it's closer to home. I'm glad that your folks have taken to it quite well, but I'm just speaking from my own experience. The thing is, if I can come up with design constraints for folks that struggle in my own experience, chances are, it's probably an easier interface for everyone. A solution for physical buttons was less of a comment on OP's grandmother's situation, and more as plus point for the fact that physical interfaces trump touchscreens when the amount of total actions you wish to take are limited. It's the same reason I prefer physical knobs and switches when I'm driving as opposed to touchscreens. I'm pretty tech literate, I work in the industry, and if this screen gives me pause to work out what the heck I want to press on it: https://imgur.com/hTnnOmB https://imgur.com/hTnnOmB then it's a no go as a general solution for everyone.
