Google Chrome OS is open source and will initially be intended for netbooks; however, the system is said to be equipped to power large desktop systems as well. The three main aspects of the operating system are speed, simplicity, and security. Although Google will construct its own windowing system, the new OS will run on top of the kernel from the open source Linux OS.

According to the Google blog post making the announcement, the OS will not be available to consumers until the second half of 2010.

As Google prepares to enter the operating system market, many questions come to mind. First of all, is this a direct attack against Microsoft since Bing appears to be making legitimate progress? Will Google’s OS exist as a serious contender to the alternative operating systems? How will consumers and computer manufacturers react? Will Google be hit with more antitrust investigations?

Although there are many unanswered questions associated with this news, one thing that is certain is that Google has just taken on a challenging mission.
