Been waiting for this. The video is a good review, it's also a very very clever ad for Google. Take note of how they start off using the old classic search with suggestions and by the end of the video they make reference to an "instant" and then they are using Google Instant. We also see priority inbox in gmail employed which is a newer feature Google rolled out. Oh and the call to South Africa using Google phone highlighting both that product and the Vuvuzela craze.
And for anyone who wants, the full zeitgeist is here since Trekkie just likes posting links/stories he finds
