In the personal-computer industry, where things change fast, one fact has been a constant for years: There are two major, mainstream operating systems for consumers. One, Microsoft Windows, runs on many brands of hardware and dominates sales. The other, Apple's Mac OS X, runs only on its maker's Macintosh computers, and has had a resurgence in popularity in recent years. Other contenders, such as various versions of Linux, have remained on the fringes.
Google's new Chrome OS aims to do everything online, turning the entire PC into a giant browser. There are advantages, Walt Mossberg says, as well as disadvantages. For example, a Chrome OS computer can't do much when it's not connected to the Internet.
Next summer, however,
Google hopes to add a third broad-based computer-operating system to challenge the duopoly. It's called Chrome OS, and is based on Google's Chrome Web browser. With Chrome, Google isn't just aiming to elbow its way into the OS business. It's hoping to change the entire paradigm. Instead of storing most programs and files on your computer itself, the Chrome OS will mainly run programs from, and require you to keep your data in, the cloud—remote servers located on the Internet. In effect, it turns your entire computer into a giant Web browser, instead of treating the browser as just one among many local programs.
The Chrome OS isn't finished, and isn't ready for broad public testing. Google readily concedes it has lots of bugs and rough edges. But the company has designed a small test laptop with the new operating system installed and distributed "a few thousand" of them to outsiders to try.
I have been using this machine, called the Cr-48, for about a week, and have some explanations and first impressions to share. This isn't a formal review; that will have to wait till the product is finished and is on commercial computers.
