Google's Chrome OS and Cr-48 is a fascinating first-step into the web-based OS world. We've studied the operating system, the hardware and the apps (or extensions) you can add to it. No one's ready to say whether or not this is the future of computing, but it certainly is fascinating. For now, we see it as an experiment that could bear real fruit. However, the best way to experiment is with lots and lots of trials. Google, apparently, agrees and is offering PCMag.com readers the chance to win 5 Google Chrome Cr-48 laptops.

To enter for a chance to win, you have to follow PCMag.com's Twitter account and tweet this phrase: "I want to join the PCMag Google Chrome Notebook Experiment!" to @PCMag. We'll collect all the entries delivered to us by Friday, Dec. 17th at 11:59 PM and then randomly select five winners.

Good luck!
