The 1st thing I was thinking about the $45 China quoted market price (which is probably lower since it doesn't include either volume or haggling) was the cost of shipping from China to the other markets. At the end of the article we see the price after shipping translate to $79, which adds approx 100% to the cost in-stores. I guess the next wave will involve ways of either making shipping and the process of importing cheaper, or just circumvent it all together with say 3d printing.
