This strikes me as a very interesting strategy. The way I read it, by installing the Chrome browser, you are enabling Chrome apps that you install to live outside the browser.

Chrome Apps amount to a Trojan horse for Google. By way of the Chrome browser, the company is essentially putting its own app ecosystem right on top of Windows and OS X. It’s a play that’s been months in the making. “There are still reasons why a developer would build a native app over a Chrome App today, but we’re working to tackle each one,” Rakowski says. Google began promoting a handful of Chrome Apps (then called Packaged Apps) in May. In July, its Chrome notification center was pushed out to Windows and Chrome OS users, allowing for alerts and pop-ups outside the browser window. And for months, Chrome’s developer channels have shipped with an app launcher that lives in the Windows taskbar — this launcher rolled out to the public today too.

The new apps look and behave much like the native apps you find on Windows and OS X. They’re built using web technologies, but also with Chrome-specific code that means they won’t be able to run on other web browsers — they’re truly Chrome apps. They can exist outside of your browser window as distinct apps, work offline, and sync across devices and operating systems. They can also access your computer’s GPU, storage, camera, ports, and Bluetooth connection. Chrome Apps are, for now, only available through Chrome on Windows or Chrome OS on a Chromebook. Mac users will have to wait another six weeks before their version of Chrome will be updated.

Will be interesting to see how this all works on top of Mac OS X.
