Centrally managed enterprise computing exists since the beginning with mainframe with dumb terminals. And you have Citrix thin client or vmware virtual client infrastructure for such purpose. ChromeOS is trying to solve the same problem, the problem of IT management rather than users need, experience and the advance of end user computing. ChromeOS if successful is not a good idea for the future of computing, where I believe an intelligent and powerful client is needed for the advancement of user-computing interaction design. ChromsOS reenforce the idea that computing is about the web with a screen and a keyboard. Cloud computing is more than just http right?
