From Apple’s press release:
Apple today announced Corning Incorporated will receive $200 million from Apple’s new Advanced Manufacturing Fund as part of the company’s commitment to foster innovation among American manufacturers. The investment will support Corning’s R&D, capital equipment needs and state-of-the-art glass processing. Corning’s 65-year-old Harrodsburg facility has been integral to the 10-year collaboration between these two innovative companies and will be the focus of Apple’s investment.
I’m probably biased because I live about thirty minutes away from Corning’s corporate headquarters, but I think this is a very smart investment. All of Apple’s most important products feature glass that was developed by Corning and there’s no other company in the world that can match their offerings.
