ChromeOS has a great separation of concerns and isolation of environments. I have my work profile and my personal profile, which are totally separate. I have my browser environment and my dev VM, which are totally separate. Different activities are cleanly partitioned.
This has obvious security benefits but also is just a really nice, simple way to manage the system. I can fuck up a dev VM without impacting anything else, I can click random links on my personal profile without impacting work, etc.
It also just does what I want it to do. I browse the internet, I program. It's good for those things. So... why Linux?
