I regard older iOS devices as akin to cars so great that one is inclined to keep them and drive them into the ground, even if they become the equivalent of the car you drive to the park'n'ride near the end of useful lifetime. Before I hand an old iPhone or iPad on to some kid in my stone broke county, it usually migrates from primary device of its kind in my household to a specialized data server - podcasts, or purchased TV shows / movies, or that one in my studio called "All Bach all the Time".
Apple gear can last long enough to become in and of itself an evangelist for the company's products and services, especially if handed on to someone else while an AppleCare+ warranty is still in force. I love it when I hear by the grapevine in this still largely rural area that a kid who got some of my old iOS gear or a laptop not only caught the coding bug but has since gone off to college, majored in computer science and joined the ranks of cybersecurity or AI programmers. Reminds me of when my gift of an Apple IIc apparently sparked something in a nephew's head and sent him along the path to becoming an aeronautical engineer. That was obviously many decades ago, but around here a computing device still sometimes turns out to be the nudge towards a ticket off the dairy farming reservation... and dairy farming definitely ain't what it used to be, what with all the consolidation under corporate farming umbrellas.
