I never understood why ChromeOS existed in the first place. To me, it would make much more sense if these devices ran Android. After all, there's no apps for ChromeOS -- other than glorified Chrome extensions, and it's not easy for developers to create ChromeOS apps (whereas if I could recycle my Android app, life would be good). Arc welder doesn't seem to work very well either.
Analogously, Apple only has iOS. There's no SafariOS.
