Apple CEO Tim Cook said Apple’s product designs are influenced by China’s consumer tastes, Bloomberg reports. As many have already suggested, the decision to release a gold iPhone last year was a reflection of that color’s popularity among Chinese users, Cook told the Chinese edition of Bloomberg Businessweek. Greater China has become Apple’s second-largest market after the U.S. Without releasing exact sales figures, Cook also disclosed that the Apple Watch is off to a promising start and drawing much more interest from app developers than either the first iPhone or iPad initially saw. A data analytics firm recently estimated the company has already sold 2.79 million Apple Watch units.
