I will not be surprised if China overtakes US to become apple's biggest market.
iPhone is so widely known across China that people in the village I was born can speak something about it.
iPhone is showed off by many as a symbol of wealth and social statue, so they all want to possess one and many high schoolers in my school in China use iPhone as their phone.
However, I'd rather like to see Xiaomi, an Android phone made by a Chinese company, to develop well, and eat most of Apple's share.
Apology for my poor English.
