According to the StatCounter, Linux on the desktop has continued to rise and remains above 4%, with this being the healthiest it's ever looked on the desktop.
So, does this include ChromeOS? I'm not sure if I'd qualify it as either a desktop OS or "Linux" (in the traditional sense). But since there's enough room for debate there it's worth asking.
They don't even count Android as Linux (despite any Android respond to uname -a with Linux version and all).. otherwise Linux would count as this planet's OS.
Also true, but Android is also rarely if ever considered "desktop". ChromeOS could be, since it shares a market with Mac and Windows laptops, which also run "desktop" operating systems.
