Poorman in Pixel OS there's a docked mode to use the tablet as some kind of smart home information screen. The OS itself is pretty much the same otherwise, and terrible for productive use with mouse and keyboard.
I tried to replace my MacOS and Fedora setup for productive work but the lack of a well integrated desktop mode, window manager and peripheral support made me sell it again. I hope things will change in the future so I can extend my Pixel 8 with a screen, mouse and keyboard. I learned my lesson and buy only things from Google for what they are capable of today, not for what they might be capable of tomorrow.
