I want to know the answer to the following question:
What is the name of Apple's hardware engineering chief who helped design the iPod?
All the background I'm provided with is that "As ordered by CEO Steve Jobs, Apple's hardware engineering chief Jon Rubinstein assembled a team of engineers to design the iPod line, including hardware engineers Tony Fadell and Michael Dhuey, and design engineer Sir Jonathan Ive.". Is that enough to answer the question?
