Apple historically had competitive advantages in vertical integration, easy to use interfaces, and innovation enhancing consumers' digital lives. However, Apple struggled in the PC industry due to wanting full control rather than open systems and poor integration with Windows. While the iPod succeeded due to its design, interface, and iTunes model, the iPhone combined music, phone, and internet capabilities along with a large app store. However, competitors now mimic Apple's designs and operating systems, so Apple must find new advantages to gain market share in PCs, MP3 players, and smartphones. The iPad still has solid long-term prospects if Apple focuses on research, development, and leading in emerging areas like cloud services and integrated home devices.
