Apple's revenue in China again exceeded  that of Europe at $10.57 billion. The Greater China region remains Apple’s second largest market after the Americas, underscoring the critical importance of this area to Apple’s future growth.With its huge consumer base and growing middle class, China is seen as Apple's greatest chance at growth as the iPhone sales boom stagnates in more mature markets like the U.S
