I expect that it can be installed on an iPad Pro
Answer me this query
-Is the mainstream, average-income consumer more likely to buy two-three devices that each cost around $1000-$2000 each but can be bought individually so that the buyer doesn't have to spend $2000-$6000 in one go, thus allowing them to spread the 2-3 $1000 purchases over several months or years?
Or is the mainstream, average-income consumer more likely to buy a single, two- or three-in-one device that costs between $2000-$6000 and has to be paid for in one single purchase?
Additionally, do you realize that Apple doing the former, separating devices into several many single-use-case products and offering fairly low-cost, $1000-ish entry-level models of these products is an incredibly successful product strategy that has yet to fail Apple?
Just to reiterate my point
-What earns Apple the most by far out of these two strategies while also making Apple products more accessible (read:affordable) to more consumers than the other strategy?
And which of these two strategies would lead more consumers to upgrade and buy new devices more often?
After answering these questions, do you still think Apple would ever put macOS on iPad?
