I'm typing this from a Pixel 2015 LS. ChromeOS is great if you're not a dev, and it's still pretty good if you do dev work on it. The problem isn't really ChromeOS (you can replace ChromeOS with Arch or Ubuntu with a little work), but that (judging from the G+ community) a lot of Pixel 2s have been RMA'd for flash disk and audio issues. If you get a good Pixel 2, it's an amazing machine. You might have to RMA it once or thrice to find that machine though.

Tbh, I would pay an additional $500 to a company that cloned the hardware but offered at least a 512 GB hard disk. I've even give up the touch screen. I'd like a quad core Skylake upgrade while we're at it, but I'm not greedy, I just want a reasonable amount of disk. They could even price it at $2000 and I'd still buy it in a heartbeat. As is, I'm still using my Pixel 2 LS, albeit with a slimline USB key pseudo-permanently attached to provide extra space. Nothing else approaches the power and battery life of a Macbook Pro if I want fully supported hardware under Linux.
