Google's Chrome OS will be released next year. The web OS definitely represents a new direction for computing--as software is moved to the "cloud" and the web becomes the preference for data storage.
Based on a report from Reuters, Dell's president for China and South Asia, Amit Midha, stated that they "want to be one of the leaders" in adopting new technologies such as Android and Chrome.
Dell did not officially commit to using the new web OS by Google, but they are definitely a strong contender.
