so, do you have any proof for this hypothesis of yours? or do you just make it up as you go along?
fact: as apple has stated in the past, most of the components industry is based in china. thats where the parts are, so thats where they are.
It was a question, not a statement!
You kidding right? Apple chooses the most appropriate components sourced usually from China, Korea , Japan etc.
Since the Japanese component is fine, who choose the Chinese supplier?
