If you’re asking whether Apple implemented multitasking in iPhone 4.0 (and you’re not a developer), then you’re asking the wrong question. Multitasking headlined the seven “tentpoles” that made up the major new features of iPhone OS 4.0. Apple is bringing the benefits of multitasking through a clever mix of new system features that extend the benefits of multitasking that Apple pursued with push notifications.
Covering such major bases as background location tracking and extending background music playback from the iPod app to Internet services such as Pandora, there are now very few multitasking needs that won’t be met with Apple’s approach that, according to the company, preserves the keys of security – an approach that Apple maintains will preserve the keys of security, simplicity, performance and battery life.
The task switching in iPhone 4.0 complement other changes that used to require a seemingly endless series of swipes to get at information. These include a unified inbox and folders for grouping apps. (It would be great if the app store let you designate an app upon downloading). indeed, these should even free up more screen real estate for another new feature – custom wallpapers beyond the lock screen.
In the Q&A following the announcement, Apple was asked about widgets, a feature available on the Mac and on Android, but not on the iPhone. Apple seemed open to implementation at some future time, particularly with the iPad and took a step toward more lock screen functionality with music playback controls. All in all, the update should go a long way toward removing many user interface inefficiencies that Apple had begun to attack in the platform, as well as make using the iPhone a smoother and less frustrating experience on a daily basis. But since at least some of these features – especially the headlining multitasking – have been available from major competitors, it begs the question whether iPhone OS 4.0 is enough to beat back not only the imrovements of the core Android operating system, but what others are building on top of it.
