People familiar with the matter said Mr. Fadell planned to take time off after leaving the company though he may still keep a role at Apple as a consultant,” Kane reports.

“Mr. Papermaster is a longtime IBM veteran, who is known to be an expert in chip design and was one of the main architects behind the Power PC processor. IBM filed a lawsuit against Mr. Papermaster late last month, alleging that he breached a noncompete agreement that he had signed,” Kane reports.
