Tim Cook's letter about Scott Forstall, Jonathan Ive

Some of Tim Cook's letter to Apple employees:

Team,

We are in one of the most prolific periods of innovation and new products in Apple’s history. The amazing products that we’ve introduced in September and October – iPhone 5, iOS6, iPad mini, iPad, iMac, MacBook Pro, iPod touch, iPod nano and many of our applications – could only have been created at Apple, and are the direct result of our relentless focus on tightly integrating world-class hardware, software and services.

Today, I am announcing changes that will encourage even more collaboration between our world-class hardware, software and services teams at all levels of our company. As part of these changes, Jony Ive, Bob Mansfield, Eddy Cue, and Craig Federighi will be taking on more responsibilities. I am also announcing that Scott Forstall will be leaving Apple next year and will serve as an advisor to me during the interim. I want to thank Scott for all of his many contributions to Apple over his career.

Jony Ive will provide leadership and direction for Human Interface (HI) across the company in addition to his longtime role as the leader of Industrial Design. Jony has an incredible design aesthetic and has been the driving force behind the look and feel of our products for more than a decade. The face of many of our products is our software and the extension of Jony’s skills into this area will widen the gap between Apple and our competition.

Eddy Cue will take on the additional responsibility of Siri and Maps. This places all of our online services in one group. Eddy and his organization have overseen major successes such as the iTunes Store, the App Store, the iBookstore and iCloud. They have an excellent track record of building and strengthening our online services to meet and exceed the high expectations of our customers.

Craig Federighi will lead both iOS and OS X. We have the most advanced mobile and desktop operating systems on the planet, and bringing together our OS teams will make it even easier to deliver our best technology and user experience innovations to both platforms. Craig recently led the very successful release of Mountain Lion.
