I suppose I'll have to download and install to be sure, but it really looks like a version of the Chrome Browser, which is designed to run on the new Chrome OS. That said, looking at the Screenshot, I can see some "OS" like features, such as the clock, or maybe a button in the browser which launches other applications.. I think I see why they're calling the OS Chrome. It's not that they're re-using the name, they're just adding basic windowing and app launching to the Chrome Browser. If you ran it "Chromeless" (Ie, without the Gnome dock, etc), you could use this as a.. Sort-of OS. That's very much not what I had imagined for a "Chrome OS", which would be much more like the fake demo video we say on Techcrunch a few weeks ago, but this would be a very Easy project to put together.
