I live in Cupertino, right between the two Apple campuses. The problem for me is too much shadow. For example, it says that the Apple campuses keep my house in shadow for much of the day, which I can assure you is not accurate. Other tall buildings cause the same problem.
It probably works a lot better in nature where all of the sources of shadow are natural mountains.
