It's been a pretty significant year for the U.S. mobile industry and its users. First, a computer and consumer electronics company essentially dictated a new business model and took device usability to a different level. Second, a shift to mobiles as "lifestyle" devices has accelerated. The expressiveness of design now is as important, if not more important, than device functions and features.
Third, a shift to "open networks" began, and even-faster innovation will be the result.
The lifestyle focus, in turn, will help drive mobile ad spending. That's partly because the mobile Internet is emerging, and partly because video, audio, games and entertainment are a bigger part of the "lifestyle" than the "work" device.
That, in turn, means many more ad-supported features, as is the case for the broader Internet and Web.
