Google is launching Chrome OS. Google is saying that the modern computer user spends so much time working with Web-based resources that the main control system for the computer should be the browser, not the operating system. Furthermore, Google declared that the Chrome OS experience will bear little resemblance to existing way that users interact with their computer’s main control program. It is expected that in Chrome OS world there would be no Win/Web every thing looks to be managed using the web browser.

Security of computer system could be an issue as everything would be maintained using web browsers.

Another important noticeable thing is Google can give Google Docs to users to store their important documents in their computer harddrive than storing on Google Docs online. Google allows to store meta information with the document which actually makes the searching very fast with in the system.

Microsoft uses indexing service to automatically index all the documents & folders created within the computer system. would that be gone in Google Chrome?

Google may also take a cue from its own e-mail application, GMail, which blends the traditional idea of having folders for e-mail with the concept of “labels.” In GMail, you can drag messages into folders to file them, or you can drag folders (or labels) over messages to categorize them. It’s the same thing, but the hierarchy people are used to in operating systems, where a file is in one folder at a time, and the folder may be nested in another folder, is simply not there. Folders and labels are interchangable and far more fluid.

It is also expected that the Chrome OS will be using the interface of Chrome browser–like a tabbed view for switching between “apps,” and the mind-reading command line (address bar in the browser). It may also evidence Google’s traditional obsession with clean (if not necessarily attractive) design and speed. The Chrome OS should be fast.
