I've found that ChromeOS + Pixel 6 is fine. I have a Fitbit Sense 2 for a watch (I hate the idea of my watch telling me I have a meeting coming up lol).

ChromeOS is great. The host OS "just works" and I have a VM/container env to do development in. It feels secure, operationally straightforward, and low maintenance.

I don't really care a ton about my phone. It works, battery is fine. It makes phone calls, plays music. idk. I care way more about my laptop.
