From the background noise, I think they shot it at the launch party a couple weeks ago. The video was shot at IFA Berlin. It doesn't show much, but it does confirm that the Aura H2O has a way to detect water on the screen and warn you that the device got wet. It looks pretty cool in action.
The Aura H2O features a 6.8" Carta E-ink screen, and recently went up for pre-order in the US with a retail of $179. My review unit arrived a couple days ago, and I hope to have a review up next weekend.
