I largely agree, except for this:

> anecdotes of the craziest mixed device ecosystems people can build

All it takes is for somebody to use both an iPad and an Android phone. iPads are relatively cheap (cheaper than many Windows laptops!); iPhones are quite expensive. That's a lot of users right there, and I think it must be at least as common as Windows + iOS users.

Right. That is not what I meant by "craziest mixed device ecosystems", and yes, I agree that Android + iPad is a common enough situation that needs good defaults that we haven't yet entirely solved for (but there are options today and hopefully it will get better). Windows "knows" it has to be a bridge device with whatever the user's phone ecosystem is, iPadOS today mostly assumes the user's phone "must be" an iPhone. From Apple's perspective that still makes sense as a useful "default" for what they consider to be their average user.
