Those charts on page 2 would be a lot more informative if they colored the bars by processor architecture. That would make it more clear that support duration trends downwards for the last few years before an architecture switch—not at all a surprising outcome. It'll be interesting to see a decade from now if the bounce back after the most recent architecture switch was immediate or if it happens over a few years. For the PPC to Intel transition, the first few Intel models were held back by only having 32-bit processors, or 64-bit processors but only 32-bit firmware. Will the M1 get 8+ years of updates, or will it have an early retirement relative to M2 and M3, or will it be all the models with only 8GB of RAM that get an early retirement?
