If you, like me, were wondering why Google thinks it needs another operating system (ChromeOS, Android, Fuchsia - which is presumably dead (edit/turns out it's not/edit)) or where it fits in with the "stack":

> ChromeOS and Aluminium Operating System (ALOS) Commercial devices across all form factors (e.g. laptops, detachables, tablets, and boxes) and tiers (e.g., Chromebook, Chromebook Plus, AL Entry, AL Mass Premium, and AL Premium) that meets the needs of users and the business.

Sounds like ChromeOS is Android for entry/thin and similar PC's and Aluminum is more upmarket/premium.

Also, to be honest, this doesn't seem like "a new OS" to me, but rather a shift in Android's roadmap and an associated rebrand to try to push ChromeOS/Android upmarket to try and expand their "Devices with Gemini/Google AI as a first-class service/product" footprint beyond cell phones.

Given the push for arm in the consumer PC space, I can kinda see why google is renewing efforts here even if you set the AI stuff aside.
