Despite its flaws, the iOS 4 update is certainly a solid one with enough new features to make it worth upgrading for pretty much everyone. Trying to live without even the most basic aspects of multitasking (notably state-saving) can be frustrating once you have used it for a while.
The most exciting part about iOS 4 is really what third-party developers will do with the 1,500 new APIs. After all, the iPhone experience has become one that is almost defined by its apps, and Apple has opened up a new world of possibilities with its latest API offerings. As we go into the second half of 2010, we’re sure to see plenty of new apps that do creative things with Game Center, multitasking capabilities, the camera, and more.
