Further to previous rumours, Nvidia has now officially confirmed it is "working closely with Google" on Chrome OS Tegra devices.

As well as Android devices, Mike Rayfield, Nvidia's GM of mobile business, has told JKOnTheRun that netbooks, or "smartbooks" running Google's Chrome OS are currently in discussion.

Google's Chrome OS is "a lightweight operating system that will initially be targeted at netbooks" while Nvidia's Tegra is a system-on-a-chip processor used in the likes of the Zune HD.

When the new OS was announced back in July, it was suggested the first Chrome-based hardware could be expected in early 2010.
