Chrome OS is Google's Linux-based operating system built around the Chrome Web Browser. It's a lightweight OS designed primarily for web-based computing within a browser window. Chrome OS is fast, secure, and resilient to viruses and malware. Official support for Android apps from the Google Play store will be widely available for Chrome OS in late 2016 / early 2017. It's currently available on the Chromebook Pixel 2, Asus Chromebook Flip and Acer Chromebook R11 on the Dev and Beta channels.
