Google Chrome Blog: A New Beta: Why slow down when you can speed up?
We're always trying to further push the things you can do in the browser. For example, we've started building HTML5 capabilities into this beta release, including video tag functionality and web workers.
Speed, Speed, and more Speed
Beyond the improvements in JavaScript execution in this latest beta, there are a host of other improvements that should help Google Chrome make the most of your network connection. For example, when you open a new web page while other web pages are still loading, Google Chrome is now smarter about prioritizing the requests for the new page -- for instance, fetching text, images, and video for your new page -- ahead of the requests from the older pages. Loading pages on this beta release should also be faster than ever with DNS caching, more efficient DOM bindings, and using V8 for proxy auto-config."
This is a good start for the Google Chrome Operating System and I am sure it will pretty much look and function like Chrome Browser.
