G.ho.st, remember it's not Ghost. It's a web-based operating system built on Flash. Although it's still in the testing phase, its functionality is pretty good, integrating various tools such as YouTube, Flickr, Meebo, RSS subscriptions, browser, Flash player, Google search, music player, Pandora music library, clock, notepad, Yahoo news and more. These features remind me of Yahoo plugins - plenty but not very practical. Also, filling out so much information during registration is really troublesome.
