"The market research firm iSuppli estimates that the Kindle's total manufacturing cost is $185. The most expensive single component is the $60 display, which Taiwan's Prime View International is manufacturing."
This story was taken up by the Brookings Institution under the title: "Amazon’s Kindle: Symbol of American Decline?" in which we read:
"...Because E-Ink could not control the low-temperature polysilicon and the fabrication of the display, it could not perform the system integration required for it to capture the majority of the value-add at that stage....U.S. will likely miss out on the future industries that may spring from shop-floor tinkering with the display and its production--“things like large flexible displays, future generations of electronic signage, and plastic electronics.”"
