With wireless technologies playing such an important part, especially for iOS devices, it's no surprise that Apple wants to devote more focus to them. The Technologies group will be able to develop and improve wireless across all of Apple's product lines, perhaps easing the ways in which those devices talk to each other. Given the improvements we've already seen, it's not hard to imagine a future where you needn't plug your mobile device into anything at all.
And lest we forget the second part of Mansfield's brief:
This organization will also include the semiconductor teams, who have ambitious plans for the future.
Semiconductors are, of course, the foundation of the processors and chips that run all of our devices. While Apple's Mac lines still rely on processors provided by Intel, the company has been producing its own chips for its mobile devices since the original iPad. That and subsequent processors have resulted from Apple's purchase of PA Semi, a small semiconductor company.
Having its semiconductor design in-house has given Apple an even deeper level of control over its products -- at least, the mobile ones. And, going forward, it seems hard to believe that Apple will leave it at that. The Mac is still an important part of Cupertino's strategy, and with all the custom work that Apple has been putting into its hardware design -- the internals of the Retina MacBook Pros, for example, or the redesigned iMac -- it's not hard to imagine the company will want to eventually go that last nanometer and control the chips for its desktop and portable computers as well as its mobile devices.
Integrate to innovate
Looking over all the changes that Apple made to its executive team, there seems to be a pretty consistent throughline: This is all about integration. Integration of the various software platforms and teams, integration of the company's key technologies across product lines, integration of online services, and integration of the hardware and software user experiences.
All this integration mirrors exactly what Apple has tried to do with its products for decades now: Take a bunch of disparate technology, software, hardware, services, and so on, and combine it into one perfect device. After Steve Jobs's death, many described Apple the company as his most enduring "product." This reorganization suggests that Cook has taken that to heart while simultaneously putting his own definitive stamp on it.
