There is so much time, effort, and physical waste that is generated by slightly redesigning phones every year purely for the sake of making sales (as opposed to meaningful improvement upon the existing design or introduction of a new hardware feature). Think not only of people upgrading for the sake of it, but all of the cases, screen protectors, and other assorted accessories cast in plastic for previous models that are garbage now.
It would be nice if we could just space these things out to 5 years or so now, because that's probably how long it takes for anything to change enough to justify a new model.
I rely on my smartphone for work, I'd rather buy a 4y old model known to be reliable than a brand knew one that ends up preventing me to call 911 or whose screen die randomly and unexpectedly.
Obviously the first clue is cars are not phones.

Most people don't care about waste so I know I am part of a small fraction.
