Disingenious ad from Google
The Nexus 7 doesn't have cellular networking. Only wifi. Google shows an ad with a boy and his father camping and using their Nexus 7 in various situations, including using network-related stuff such as Google Earth.
The punch line is that they're in their own backyard, well within the reach of the Wifi of their house. Well, what kind of ad is that? For unknowing users, it would look as the Nexus 7 is ideal as a networked device when camping, and for us who knows - it says that camping with the Nexus 7 can only be done if you keep within the reach of your wifi. Just... stupid.
