Despite knowing he was dying, Steve Jobs, former CEO of Apple, worked for more than a year to make plans for four years of new products that he believed would maintain the company's future.    It was also revealed that Jobs fought hard to get plans approved for a spaceship-style company headquarters in California. It will be big enough to hold 12,000 employees in a park-like setting near the existing base in Cupertino, the global headquarters of Apple. He appeared at a town council meeting in June to promote the planning.               He was also overseeing   the development of the delayed iCloud project, which will allow Apple users to store their music, photos and other documents remotely, and designing updated versions of the iPod, iPad, iPhone and MacBooks, ensuring that at least four years' worth of products will go smoothly.
