Download Google Chrome OS for free.
If you like living your digital life in the browser, then Chrome OS could be a clarion call that's hard to resist. It's fast, it's geared for an Internet tether yet able to function on its own, and it's a bold step into the future of how operating systems work. However, it's untested on a large scale, and concerns about its effectiveness and utility are not without merit. Review:
Welcome to the Chrome channel. Available on laptops from Samsung and Acer, Google's new operating system is all Chrome, all the time. If you absolutely loathe the Chrome browser, it's highly unlikely that you'll enjoy this operating system, because it's basically Chrome on performance-enhancing drugs. On the other hand, if you love Chrome, then Chrome OS is a big heaping helping of Chrome with some extra Chrome on the side and then Chrome for dessert.
When the limited-edition Cr-48 laptop and beta version of Chrome OS were released in December 2010, the best things about the operating system were telegraphed by the browser, and Chrome OS beta's shortcomings were more related to anemic hardware than anything else. The operating system did have definite problems back then, most notably a missing local file-browsing tool. As you'll see in the review, most of the operating system gaps have been fixed with varying results.
It's also important to note that, like Chrome-the-browser, Chrome-the-OS has an open-source sibling available, called Chromium OS. If you like coding and developing, this is likely going to be your best bet for exploring what makes Chrome OS tick. - Source CNET.com
