The only use they show in the add that would make the typical person thing you needed Wi-Fi was the google maps part. But because you can pre-cache/download maps onto your Nexus 7 to be used when you don't have Wi-Fi it's actually doable without. Everything else they show is really stuff you could easily download to your tablet beforehand. the movie, book, chess game, even the info on the frog and dinosaur...all that stuff doesn't necessarily need Wi-fi if you have the information on your Nexus7 already. If they had shown them using google or doing a video chat with someone then I'd have called them on it...but they were careful not to show those kinds of 'Wi-Fi' only uses. Not sure if this is on tv yet or if it's just online. They'll probably run a shorter 30 second version on tv I should think.
