Many of these devices aren’t actually fungible commodities though.I tried to buy a phone in the $200 range and Android phones were so much worse than used iPhones. I they would drop calls and freeze on the dial pad during long calls where I was on hold. Tried two different models and had the same issues. I could have tried a used $200 Android but I was not wanting to try for a third Android. All I wanted/needed was to make important calls.
So I guess I don’t see them as commodities which implies fungibility.
