Last week, Apple's Steve Jobs made a design presentation — not to masses of swooning tech journalists, but to the Cupertino, California city council. What Jobs unveiled this time was Apple's future corporate headquarters. The design, by celebrated architect Norman Foster, is shaped like a giant glass doughnut with curved windows all around. Kurt Andersen spoke with design writer and curator Phil Patton about what this fantastic, futuristic building could mean for Apple and the design legacy of Steve Jobs.
