Google have just announced that the Aura updates are rolling out to official Chromebooks now, Aura being the new windows manager for the previously browser dominated OS. Aura adds a more traditional, albeit lightweight, desktop that still connects to all the web apps that Chrome OS is known for. The open source community will be happy to know then that this new feature is available in the open source version, Chromium OS.
It’s actually been available for a few months now, with Google doing their usual battery of tests before deciding to roll it out to users of the commercial Chromebooks. You can add Aura to Chromium OS when building it, with a simple walkthrough provided on the Google Code Page for Aura.
Aura might well be a way to reignite interest in Chrome OS, giving users that felt alienated by the browser only view a more understandable way to adapt their workflow. You can get the source for Chromium OS from the projects website.
