After several months of great fun exploring several Android boxes and lots of incredible pointers and keyboards, I relaxed and went with Firestick. Netflix and everything I needed was available with just Android, but it is still the wild west with no uniformity between apps. Amazon enforces outstanding app to app HMI uniformity. A few, like maybe PBS, lag a bit behind, but they are catching up.
The latest Firestick with ethernet added is trouble free.
I’m back in the Android world trying out converting old laptops. Even more fun and much more challenging. The latest Google office type suite makes it worth the effort, though.
