Sure! On install, a few things didn't work: trackpad, keyboard backlight, touchscreen, and I think screen brightness. However, https://github.com/tsowell/linux-samus solved all these problems. There are a few details to iron out (as described in the README) but at this point it's fully functional for me.

Great, thanks! If you monitor hardware using powertop, do all devices enter into sleep modes when appropriate? Does the Pixel overheat?

No problems with overheating, so far it's never even gotten uncomfortably warm. Battery life is good enough relative to my old laptop that I haven't bothered checking power usage carefully yet, but here's powertop's output:
