I could see using this during a vacation when I'm separated from my spouse for a short time. I'm going shopping for groceries and she takes a short walk, and we can still stay connected, she shows me the landscape and I ask her what she thinks of that cereal. Or me in a shopping center, looking for a new camera/whatever, and she shows me what kind of dress she thinks of buying in a totally different store. These kinds of "still connected, but following our own paths" I don't know if it's going to be successful. What if I rather be there in person? What if this sort of semi-connection is not compelling and feels like making life one dimension shorter? Who knows, but it's a far cry from useless.
