Google Chrome OS is a new open source, lightweight operating system created by Google to be used primarily for web applications. It is based on Google's Chrome browser and the Linux kernel. The OS is fast, simple to use, and secure. It is targeted at netbooks initially and will run on both ARM and x86 chips. Google plans to partner with PC makers and offer the OS either free or at a nominal charge in an effort to compete with Microsoft's Windows operating system and capture market share.
