Apple has created a new division within the company focused solely on the iPod. Jon Rubinstein, who has led Apple’s hardware engineering efforts, will run the new division. Timothy Cook, head of Apple’s worldwide sales and operations, will lead a newly organized Mac division, according to Reuters. Tim Bucher, head of Mac system development, will take over hardware engineering. The moves were announced today in a company-wide internal email sent by Apple CEO Steve Jobs. “This organizational refinement will focus our talent and resources even more precisely on our industry-leading Macintosh computers and the wildly successful iPod,” an Apple spokesman said.
