Not sure why you’d want to switch any of the other stuff because the iPad, iPhone, and Apple Watch are clearly superior to almost anything else you can buy in their categories.

That said I have a chrome book in addition to apple everything else and I find that the Google suite interacts ok with the apple stuff. It may be much better on an Android but I’m not poor so I’ve never owned an Android and wouldn’t know.

If you wanted to try a cheap android burner phone the Motorola G series of phones can be had for a couple hundred bucks and are well reviewed. But again I’m not poor and have never purchased one myself.
