Chrome OS is Google’s very own computer operating system. Although the very first Chrome OS notebook is merely a prototype many news outlets have begun receiving them to test, review and giveaway. CNET has 5 Chrome OS Notebooks to giveaway for free. Here’s how you can enter..

David Carnoy explains that this giveaway won’t work the same as the usual “leave a comment to enter” but will use Twitter instead. No surprise here right? Right. The requirements to enter are that you follow CNET on twitter and tweet a specific message. Simple enough. Head to CNET’s Chrome OS Notebook Giveaway page for more on that.

Worth noting: This particular contest is open only to persons 18 years are older and who live in the United States. Again, see contest article for complete details and updates.
