With Linux in ChromeOS, this thing now runs basically 3 OSs (Chrome/Web PWAs, Android, Linux) in one environment. What this means is that I open my app drawer, and I see app icons I can launch. I don't know or care what actual OS those apps are running on! It could be a PWA or an android app or a linux app and it works and runs the same as any of the other apps. All without compromising on the security isolation benefits of ChromeOS.
