The bottom line: If at first you don't succeed, update and update again. Regular Chrome OS updates over the past year have made it faster, with better offline support and more compatibility with traditional file formats. But it's still only for die-hard Googlers.
Welcome to the Chrome channel. Google's operating system started off last year as being little more than all Chrome, all the time. Updates made over the past year have given Chrome OS users better file format support, faster navigation, revised menus, dramatically improved offline abilities, and a new, traditional-looking desktop.
But if you loathe the Chrome browser, it's still highly unlikely that you'll enjoy this operating system. 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.
Like Chrome-the-browser, Chrome-the-OS has a freely available open-source sibling, 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.
Please note that because of the similarities between the Chrome browser and the Chrome OS, parts of the Chrome review have been reproduced here where applicable.
Installation is not an issue for the Chrome OS since it comes preinstalled. There is a simple setup procedure, however. When you start up your system, it's recommended that you sign in using a Google account. You're not required to, and if you'd prefer you can opt for the Guest mode.
Guest mode in Chrome OS cleverly uses the Chrome browser's trackless browsing mode, called Incognito. Incognito prevents guest users from leaving any traces of their session, as well as keeping them from making any changes to your apps and other settings.
After choosing your log-in method, you're asked to read through and accept the EULA. This will only appear for the initial log-in; it won't show up for subsequent uses and users. Next, you can take a photo of yourself with the Webcam, use a provided icon, or use your current Google account avatar. Gone from previous versions is the mandated Webcam photo.
Chrome then takes anywhere from 30 to 60 seconds to synchronize your Google settings, if any, and then the computer is ready to be used. There's no doubt that the EULA is annoying, but we've never seen another new, unused operating system start so quickly.
Google has clearly spent some serious time developing the new interface. It looks and feels like a personal computer, finally, where before it was little more than a full-screen browser. There's an actual desktop that looks a bit cribbed from Windows 7, with Chrome-the-browser pinned to the far left of the Launcher, and other apps pinned right next to it.
The desktop itself shows only your background by default, but a Tic-Tac-Toe-style icon on the Launcher reveals all your installed apps over the desktop background. When you install an app, it'll appear here. The lower-right corner shows the time, Internet connection status, battery status, and shows your Google account avatar to indicate who's logged in. Click the avatar to show shutdown options and reveal more information and settings.
All the Settings have been moved to open in their own tabs, but you probably knew this from using Chrome-the-browser. Changes made in the browser tend to be reflected in Chrome OS about a month or so later.
The look of Chrome has changed remarkably little since its surprise debut in September 2008. Tabs are on top, the location bar -- which Google likes to call the Omnibar -- dominates the minimalist design, and the browser has few visible control buttons besides Back, Forward, and a combined Stop/Reload button.
On Chrome OS, the upper-right corner of the browser hosts a square icon and an X. The X is to close the browser window. Drag the box down to minimize the browser, drag it to the edges to "snap" it to the side and make it half the width of your screen, or click it to switch from windowed mode to full screen. The window snap is another cue taken from Windows 7, but it's clever and intuitive one, and works well in Chrome.
The interface's strongest point is also its weakness. What works well in the browser works well here, but the faults of one are reflected in the other too. Some controls, such as page zoom, are readily available from the "wrench" options menu. Others, such as the extension manager, are hidden away under a Tools submenu. Hiding essentials like that remains an odd design choice to make. As is true about every aspect of this operating system, updates are much more likely to tweak the layout and design of the interface.
Chrome's extensions are fairly limited in how they can alter the browser's interface. Unlike Firefox, which gives add-on makers a lot of leeway to change the browser's look, Chrome mandates that extensions appear only as icons to the right of the location bar. The benefit maintains a uniform look in the browser, but it definitely restricts how much the browser can be customized.
Even with its limitations, the browser interface design has remained a contemporary exemplar of how to minimize the browser's screen footprint while remaining easy to use and versatile. The new desktop, on the other hand, finally brings to Chrome OS a sense of familiarity that is essential for any new PC experience.
Chrome OS isn't quite as reliant on the Internet as it was before, but it's still reasonably crippled without one. This is a vehicle, first and foremost, for leading a Web-based existence. As such, what Chrome OS does is create a space where Web-based applications can function and thrive. The operating system itself doesn't do much -- it's a browser.
However, it's a heavily modded browser, and it achieves its main goal of getting you on the Web as fast as possible. This comes from both the solid-state drive (SSD) on your Chromebook or Chromebox, and the various optimizations that Google has been building into Chrome. This is where the second bit of genius in the Chrome OS comes in: because everything is Web-based, you can log in to any installation of the operating system and instantly have all of your apps, settings, and other personalizations at your fingertips. That's still an incredible feat.
It's an important one, too, as Chrome OS improves with each regular iteration of the operating system. In Chrome OS's first year, it updated eight times. Things that were buggy originally, such as touch pad support on the demo hardware Cr-48, started to work properly. Many Chrome-safe extensions that wouldn't install on the Chrome OS beta, but would on the browser, now work in Chrome OS.
The Chrome OS has a usable file-browsing system, accessible via Control-M or under the Tools submenu of the Options wrench. When you take a screenshot using the Ctrl-Next Window button, for example, you'll find it saved locally via the File Browser. It now supports a wide range of popular file formats, including PDF, PPT, DOC, ZIP, XLS and RAR, and the newer Microsoft proprietary versions of those formats like PPTX.
Google has also leveraged its successes in other departments to benefit the Chrome OS. Google Plus hangouts, for example, come as a preinstalled app so that you have video conferencing as an option right off the bat. Google's notorious for not always having good integration between its services, so this -- and solid Google Play integration -- are welcome improvements.
Famously, Google has killed the Caps Lock key and replaced it with a dedicated Search key. Tap it and a new tab will open, with the cursor ready in the location bar. What's less well-known is that you can remap the Search key to Caps Lock, and that Google makes it easy to do through the Settings menu under System, then Modifier keys. Here you can modify the bindings of the Control and Alt keys as well.
The default settings for the hot keys are one of the best things about the Chrome OS. Hold down Ctrl and Alt with the question mark key to bring up a color-coded map of combinations that you can use. The map and colors change depending on which key -- Shift, Control, or Alt -- you're pressing.
Google is to be commended for building an operating system that goes from sleep to fully functional in what feels like a second. There's simply no lag time, and the updates have fixed previous lagginess in logging in and out. Your Chromebook or Chromebox may just be the fastest PC you've used when it comes to booting, shutting down, and logging in and out.
Two other low-profile but well-executed features in Chrome are autoupdating and translation. Chrome automatically updates when a new version comes out. This makes it harder to revert back to an older version, but it's highly unlikely that you'll want to downgrade this build of Chrome since this is the stable build and not the beta or developer's version. You can toggle the build among the three under About Chrome. The second feature, automatic translation of Web pages, is available to other browsers as a Google add-on, but because it comes from Google, it's baked directly into Chrome.
Already mentioned a little bit, the biggest OS hang-up in the operating system is offline support despite the improvements. Chrome OS will support the core Google apps of Gmail, Google Calendar, and Google Docs offline, but for most of your other apps, you'll be left in the dark. That might not be an issue on the Chromeboxes, Google's answer to the Mac Mini, but for the portable Chromebooks, prepare for a severely hamstrung experience. Anyone outside of the cloud crowd likely won't be comfortable with it.
You can print with Google's cloud-printing feature, accessible via the common printing hot-key combo of Control-P. Google has anticipated the problems that still plague cloud printing, and so it offers instructions on how to do it. Still, most people will probably find the process way too fiddly because what's simple to print off a basic Windows 7 Netbook will take effort to set up properly from a Chromebook. Cloud Print does now come with access to FedEx stores in the United States, which is a nice improvement for remote printing.
Google is basing most of its claim of a secure operating system on a new feature in Chrome OS called "verified boot." Chrome OS will check its own integrity when booting, and if it detects any changes it will allow you to restore a last-known good configuration.
The following benchmarks are of the original version of the Chrome OS that shipped on the Cr-48. There have been significant improvements since then, and CNET will update the results below as soon as possible.
Benchmarking the first beta of the Chrome OS proved to be a bit tricky. It's hard to measure the impact of various essential programs, such as a productivity suite or media player, on the operating system because they exist largely in the cloud. However, because the operating system is also the browser, we were able to run browser benchmark tests against it and compare them against the same version of Google Chrome, but running on a Windows 7 laptop.
These tests are admittedly not a direct apples-with-apples comparison. Google has not yet released the specifications of the Cr-48, saying only that it's running an Intel Atom processor. The Windows 7 x86 laptop we used is a high-powered Lenovo T400 laptop, running on an Intel Core 2 Duo T9400 at 2.53GHz, with 3GB of RAM. However, they do provide a snapshot of what the Cr-48 with Chrome OS is capable of at this time, and we can expect these numbers to improve as Google continues to upgrade both the Chrome OS and Chrome browser. The two laptops were running nearly identical versions of the Chrome browser. Tested in December 2010, the Cr-48 was running Chrome v8.0.552.341, whereas the Lenovo was running Chrome v8.0.552.215. (By comparison, the version of Chrome OS available in early June 2012 is 12.0.742.77.)
What we can see from these tests is that the hardware will have a massive impact on the performance of both the browser and the operating system. This isn't news, but the fact that the Cr-48's version of the Chrome browser was so dramatically affected in all three tests tells us that what hardware future computer makers choose to support Chrome OS on will almost definitely change how well the public receives it.
We were also a bit surprised that the full cold-boot and log-on procedure, not counting the time it took to type in the log-on password, averaged to nearly 30 seconds. Some Windows 7 computers have, anecdotally, been found to boot up cold in similar times. As mentioned earlier, this time had been cut in half by early June 2011.
Of course, the real time-saving feature of the Chrome OS is the resume from wake, which is practically instantaneous. As long as the computer isn't shut down, it will wake extremely quickly.
Although Chrome OS does update regularly, this second major iteration is much more usable than where the operating system was a year ago. The quirkiness of a PC without the traditional touches of a PC desktop have been replaced by something recognizable and usable. As long as Google continues to support the project, Chrome OS will keep improving. One day, and perhaps sooner rather than later, it might even be ready for all.
