Exercise through everyday walking likely plays a key role. Rural Americans drive everywhere and their most significant walking typically will take place only within stores while shopping.
What gets me is how Apple markets the improvements in the M series processor. They iterate on these on a yearly basis, yet do not upgrade base model RAM for near a decade.RAM is quite often the limiting factor for current computer longevity. This is especially true of Apple computers as RAM is non-upgradable.
Apple at a minimum should create a cadence of RAM upgrades to coincide with processor upgrades to at least some extent. Otherwise they are selling base model computers that are going to require most users to replace sooner.
Conflicts with Apple's environmental efforts.
I assume this will be lower cost through plastic casing, M1, and low RAM/storage.
Currently the M1 is sufficient for 90%+ of the population (IMO), it is the RAM/storage that will outdate most Apple computers. If Apple sells this in the $599-799 range with 8GBs of RAM that would be a solid offering for most K-12 schools.
