How do you expect to face competition from general-purpose, high-resolution E-Ink displays appearing on the market now? They are getting to the point where it would be within the ability of an average computer hobbyist to mount one on their wall along with one of the many 'HDMI stick' computers.

Your product looks very polished already, and is considerably cheaper than such general purpose displays right now. However, the E-Ink display market is (finally) becoming mainstream, which makes me wonder where you'll go from here.

No problem if your response would be too sensitive to share in public; good luck with your business in any case!
