I thought the reason Apple was getting out of the entry-level tablet market, was that it was being commoditized by dirt-cheap Android tablets that—at least for the particular things people want a tablet for—do all the same things an iPad does. (They don't have the same third-party app ecosystem, but if you're just using an iPad to consume content using the web browser/book reader/etc., there's no difference.)
In other words: presuming the educational software isn't already there either way, and still needs to be built—wouldn't Kindergarteners be served just as well by the iPad dying, the development of such software moving to Android, and the kids ending up with a stack of $50 tablets from AliExpress rather than $299 iPads? (Easier for low-income-area schools to get ahold of, too!)
