If Bloomberg's theory were true and the price of Apple's devices was the major issue here (and not the Chinese economy) then we would expect to see similar sales drops outside of China, and we have not. Also, we wouldn't expect to see falling sales in China across all of the device manufacturers (even those selling budget devices) inside China as shown in even this article. The reality is that the major factor here is that Chinese consumers are cutting way back on spending due to economic uncertainty inside China. It's something that has been discussed in the media since last year.
