I do find it interesting how Apple's QC seems to be lacking this year. Both the iPhone 4 and iPod touch 4 have more than their fair share of issues. Perhaps it's time Apple switches from Foxconn to a better manufacturer (perhaps US based?). I'd gladly pay more money to have a guaranteed quality product. and I've got to wonder if it really would cost apple that much more, since I'd imagine they wouldn't have to supply nearly as many warranty exchanges as they currently do.
I think just like lots of companies Apple will gather feedback , and in mid gen/run change if needed the manufacture of parts.
happens in any industry.
