Debating what Apple "should" do is a of the
wouldchuck fallacy where you wish for ponies instead of imagining them.
Apple's current situation reminds me of comic books around fifteen years ago: DC and Marvel were huge, but they had priced themselves out of the reach of youth. (Raise your hand if you remember comic books being sold from spinner-racks at gas-station convenience-stores. They're a;; gone now, because no kid was interested in spending five bucks on a skinny magazine half full of ads when manga is now much more interesting, if that's their thing.) Meanwhile,
Apple is down to 16% of the education market, and virtually none of that is K-12, which it used to dominate. They've lost the free advertising to millions of kids while simultaneously acquiring a bad reputation for locked-down hardware that no one can affordably repair. And Google is flood-filling the globe with Android tablets costing well under $100.
Ah well, "The Producers"-style scheme of offloading onto Class-C common stockholders seems to be proceeding nicely, so they have that to look forward to.
