From the New York Times:
A ubiquitous city is where all major information systems (residential, medical, business, governmental and the like) share data, and computers are built into the houses, streets and office buildings. New Songdo, located on a man-made island of nearly 1,500 acres off the Incheon coast about 40 miles from Seoul, is rising from the ground up as a U-city.
Sounds like a ubicomp researcher’s dream.
