Oppenheimer reiterates Perform rating - Firm has argued that Apple is an interface expert at its core. They believe that great innovation in and implementation of human interface technologies are why its products consistently exceed consumers' expectation and surprise competitors. iPhone jump-started an entire mobile ecosystem, in which software and service companies thrive. But now, firm is seeing those companies threatening various aspects of Apple's platform. Today's Worldwide Developers Conference (WWDC) will give Apple a chance to reassert its competence as the likes of GOOG, FB, and AMZN work to beat Apple in its own game (interface). As firm outlined in long-term predictions on Apple, it is important Siri is opened up to third parties, and firm believes we will get this at WWDC.
