You don’t have to be an Apple fanboy or fangirl to give Apple Inc. credit for redefining mobile gadgetry and its surrounding industries. First the company used the iPod to reshape the music industry and strongly influence how we acquire and consume tunes. Just count the number of people wearing iPod-connected earbuds in a subway car. Then the iPhone rewrote the cellular telephone industry manual, while opening the world’s eyes to the potential of being connected to the Internet nearly everywhere, all the time. It’s happening again with the iPad, where electronic publishing is evolving right before our eyes.
It took some additional months, but Apple eventually released a genuine software development kit (SDK) to allow third-party programmers to create native applications for what was then called the iPhone OS. Part of Apple’s task was also creating the App Store to distribute apps—yet another industry-transforming effort. Many existing Mac OS X developers rejoiced because the iPhone OS was derived from Mac OS X. The iPhone SDK was based on the same Xcode tools that Mac developers had been using for some time. The language of choice was Objective-C.
