Even if the sets were made in Japan/China respectively, it sounds more like a ploy to jack up the price to me. It reminds me of some of the stunts I've seen car dealerships attempt with new models.I am now in the market of buying a large HDTV. I went to a store and found two identical TVs being displayed side by side. However, there is a price different. When I asked the sales, he told me that they are the same product but one was made in Japan and the other was made in China. Perhaps Apple should do similar things.
Check the manufacturer's web site/reviews, as MSRP is MSRP, despite country of origin. They probably moved production to China to save themselves cash, and increase their margins. Customers are very likely a distant afterthought in the decision.
