Honestly, how much technology is contained in an e-ink display? Americans would rather devote their attention to biotech and microprocessors. We are world leaders in the first field. The second field is also a multibillion dollar U.S. industry, with many applications, including high speed computer architectures, digital signal processing, etc. There are very few new breakthroughs awaiting e-ink technologists that would motivate most people to ditch their existing readers.
