I saw this article linked up at kurzweilai.net , where it is mentioned that “Amazon has acquired Touchco, a New York start-up that was developing flexible, transparent, force-sensitive multitouch panels.”
The article is titled “Is Amazon Building a Superkindle?” and states that Touchco’s technology “could potentially enliven a new round of touch-screen devices. Instead, it might breathe new life into one device in particular: Amazon’s Kindle.”
