Hey! Thanks for the detailed reply. What I don't get is: ChromeOS is open source, so why do all these things only work on certain hardware? Isn't there a way to install ChromeOS on any laptop today and already use Anroid apps et al, without said machine being a Pixelbook?

I have a machine that is not an official ChromeBook and I'd love to install ChromeOS with Android support to try it out. But I've done quite some google-fu and could not figure out whether this is possible (and how I'd set that up).
