Yes, they made ipad mini, thinner iphone and macbook with retina display. But can this be really considered as an "innovation"? it's more an evolution of a product than an innovation.
Retina MBP: Well, it is the use of an existing technology in a new way or form that isn't yet on the market/. I would call this an innovation. Especially since other manufacturers have or are now looking into introducing this technology too.
I wouldn't call thinner myself an innovation, but the technology needed to produce the iphone is (matching of components by camera). There are different types of innovation: process innovation, product innovation and a number of other ones.
For us consumers these can all play an important part. Product innovation changes our user experience, whiole process innovation can make the products cheaper.
It's all innovation. Whether we personally like the innovation part and can use it is another matter. People that don't care about retina don't consider it innovation, whereas designers probably would.
This is what these arguments are about. Opinions and lack of knowledge about what innovation really is.

I think a major source of cost increases for Apple is Chinese labor rates which have been increasing at over 15% a year relative to the Dollar. Apple has partner factories in that jurisdiction for displays, boards, assembly, and other logistics and materials layers. As I understand it Apple is responsible for employment of almost one million people, at least a big part of their year of work. This trend is continuing and at some point Apple will have incentive to do manufacturing at home again.

Agree, but that will take a long time, because US wages are still too high and the US can't match the manufacturing accuracy necessary.
A more worthwhile strategy for Apple is to move their production into the more rural parts of China like car manufacturers have done or go to Vietnam or Thailand where wages are still low. The problem is that here there is not yet much tech manufacturing and capabilities are on a low level.
