I've seen people mention that the demo runs on ARM, but I can't see how that works.
As there is no build of Chrome for Windows ARM as far as I know. And the things isn't available from Mozilla either, which I assume would be the Firefox-button in the tray at the bottom.
It's at about 2:03:48 in the Mix stream. There is no Chrome or FF logo in the taskbar. Its the machine they use to do the last demo. It's not the machine used in the picture on the website linked to from this story.
