No idea why they still run the 8th gen Intel on these things. Dell and everyone SMALLER can update yearly with new products but Apple is two years old on the cpu. Half of me thinks they’re going ARM to eliminate comparisons. Every Gen is the latest even if it’s a couple years old.
Dell and everyone smaller depend on whatever is available. They don't have the resources to be better.
When Mac OS X was new, Apple was using PowerPC processors and the line went from a huge jump in power to an unsteady set of steps forward AND backward until they couldn't count on Motorola or IBM and went to Intel. When Apple brought out the 12 inch MacBook with the m3 processor and realized how awful it was, they knew that it was time for something better and less expensive--inside, at least.
Now, Apple have a chance to use their own experience developing their own processors, and through careful cooperation (they don't do that any better than Microsoft did), they can fuel their own progress.
Those millions of phones and tablets, plus macOS Big Sur, could show their product lines to finally be an integrated solution.
I don't believe that it's going to work out that well, but anything is possible.
