There are a few other networks you can use here if you're so inclined:
http://www.eink.com/contact_us.html I wouldn't use the email address there though, it directs to a PR firm.
I read a few days ago that EInk had a bigger hand in the yotaphone2 (a dual screened device with an EInk screen on the back) than as merely a supplier, though I'm not sure what that role was. That combined with their showing at CES tells me they really want to expand their presence. Customer feedback isn't guaranteed to ever filter to decision makers, but for a company actively seeking new markets, it just might.
