What the hell is Google Chrome OS?
Here's what Google says: "Google Chrome OS is an open source, lightweight operating system that will initially be targeted at netbooks" and "most of the user experience takes place on the web." That is, it's "Google Chrome running within a new windowing system on top of a Linux kernel" with the web as the platform. It runs on x86 processors (like your standard Core 2 Duo) and ARM processors (like inside every mobile smartphone). Underneath lies security architecture that's completely redesigned to be virus-resistant and easy to update. Okay, that tells us, um, not much.
After all, Google's Android is a mobile OS that runs on top of a Linux kernel. But Chrome OS is different! Android is designed to work on phones and set-top boxes and other random gadgets. Chrome OS is "designed to power computers ranging from small netbooks to full-size desktop systems" for "people who spend most of their time on the web." Hey wait, they both run on netbooks? Hmm!
Since the official blog post is all Google has said about Chrome OS and it doesn't say much, let's do something I learned in college, turning tiny paragraphs into pages of "deep reading."
It seems like there are two possibilities for what Chrome OS is, on a general level. The more mundane—and frankly uninspired—possibility is that it's essentially a Linux distro with a custom user interface running the Chrome browser. As someone quipped on Twitter (sorry I don't remember who), if you uninstall everything but Firefox 3.5 on Ubuntu, would that be the Firefox OS? What's the difference between Chrome OS and a version of Chrome with Google Gears on Intel's pretty Moblin OS?
The other possibility is more interesting. Look at this closely: "Most of the user experience takes place on the web." The software architecture is simply "Google Chrome running within a new windowing system on top of a Linux kernel." That sounds familiar. A lot like Mike Arrington's CrunchPad, actually, which boots directly into the WebKit browser running on top of Linux.
