Digitimes just posted a joint interview of E-ink chairman Scott Liu and Hanvon chairman Liu Yingjian (no relation). There's not much in the way of nitty gritty details, but there is this:
Q: Is there a concrete plan regarding cooperation between EIH and Hanvon for the educational market?
Liu Yingjian: The color e-book reader using EIH's EPD will be tried out by a class of 500 students in Shanghai in the semester starting in September 2011. But trial use of e-book readers in classroom has already started in Yangzhou. We are now able to meet the two basic requirements for the educational market: color display and handwriting input.
