While on the surface this is great, I also find it concerning in the way this is going. First, you can only access this feature (for now) on a Pixelbook. This is not Android where patches are delivered first on Google's own hardware, or is it? Then Chrome OS runs no 3rd party apps, but it runs Chrome 'Native' code, which is being phased out, where Chrome acted as a VM. I think Google wanted this to happen very much but opened all sort of backdoors into managed deployments of Windows and macOS. Then ChromeOS started supporting Android apps, although the experience is very much like running an emulator. Now it can run Linux on a VM. Fair enough, but it can run Linux only if it's Ubuntu. Ubuntu is fine but it's not the only choice for Linux, and with good reason.
