The Google Chrome blog announced just recently that they are planing an operating system. Initially geared for netbooks, but I'm sure there's more in plan. I'm guessing they wpn't target full blown computers for awhile, but this is probably an extension of Android that Google aready has for the cell phone market.
Google Chrome OS is an open source, lightweight operating system that will initially be targeted at netbooks. Later this year we will open-source its code, and netbooks running Google Chrome OS will be available for consumers in the second half of 2010. Because we're already talking to partners about the project, and we'll soon be working with the open source community, we wanted to share our vision now so everyone understands what we are trying to achieveGoogle Empire marches on.
