And in both cases, Chrome OS and Android, the fact that Linux is running underneath has zero value for the Web and Java developers targeting the respective OS.
Google can replace it by something else and they won't notice.
This is just a Pyrrhic victory, but geeks haven't yet realized it seems.
Ironically, the only "distro" that has a real chance of success is Chrome OS, because everything is moving to the web, but also because Google made it ultra simple, secure and zero maintenance. It can also run Android apps, so that's interesting.
