Lifehacker tells us that Google will be be releasing its free, open-source Chrome Operating System later this year. Google says:

We’re designing the OS to be fast and lightweight, to start up and get you onto the web in a few seconds. The user interface is minimal to stay out of your way, and most of the user experience takes place on the web. And as we did for the Google Chrome browser, we are going back to the basics and completely redesigning the underlying security architecture of the OS so that users don’t have to deal with viruses, malware and security updates. It should just work.

Chrome OS is going to be netbook oriented in its earliest version, and the idea apparently is ultimately to replace PC software with on-live Google applications like Gmail and Google Docs.

Persuading users to give up the familiar isn’t easy, but Microsoft has done a fine job lately, particularly with Vista, in creating a real opportunity for anyone able to offer more speed and convenience.
