Sick Steve Jobs reportedly working at home on new products

Chief Operating Officer Tim Cook runs the day-to-day operations at Apple, these people say. But Mr. Jobs has continued to work on the company's most important strategies and products from home, they say. He regularly reviews products and product plans, and was particularly involved in the user interface of the new iPhone operating system that Apple unveiled last month, these people say.

Apple co-founder Mr. Jobs, who is considered the company's creative leader, is also involved in the development of future projects, they say. People privy to the company's strategy say Apple is working on new iPhone models and a portable device that is smaller than its current laptop computers but bigger than the iPhone or iPod Touch.
