As part of its effort to graduate its Chrome browser to the upcoming Chome OS, Google is working to add device orientation to the browser's capabilities. Not that orientation — the ability for an app or OS to know that up is up and down is down — is all that revolutionary of a breakthrough. Developers have been tapping to that ability on the iPhone (UIDeviceOrientation) and Android-based devices (SensorManager) for some time. But adding it into the browser itself is another step towards the Google Grail: the browser as operating system.
