Yeah I'm absolutely the market for this thing. We have an old Google Home that we use as a digital photo frame and Google has progressively destroyed every other piece of functionality we once used on it.
My only complaint is that a truly environmentally friendly company (like Apple claims to be!) would make this OS available for old iPads. I'm quite sure they're capable of running it (or at least a stripped down version thereof) and lots of people have old iPad Minis sitting around.
