An anonymous reader writes with this interesting snippet about the state of mobile tech in China: "Apple Chief Executive Tim Cook believes that 'over the arc of time' China is a huge opportunity for his pathbreaking company. But time looks to be on the side of rival Samsung Electronics, which has been around far longer and penetrated much deeper into the world's most populous country. Apple this week said its revenue in Greater China, which also includes Hong Kong and Taiwan, slumped 43 per cent to $4.65 billion from the previous quarter. That was also 14 per cent lower from the year-ago quarter. Sales were weighed down by a sharp drop in revenues from Hong Kong. "It's not totally clear why that occurred," Cook said on a conference call with analysts. Neither is it totally clear what Apple's strategy is to deal with Samsung – not to mention a host of smaller, nimbler Chinese challengers."
