While the color screen is a neat trick, in practice, in an e-reader, for this purpose, I have to conclude the colors (which are faint) were not worth the sacrifice of grayer screen background, less resolution, and slower/more complicated refresh.
All that is to say, my experience with the Boox tablet makes me feel like this Daylight Computer is on the right track with its design choices. While I don't quite have the disposable income to turn around and purchase another tablet so soon after spending my money on a different tablet, if I could do things over (or if my current e-ink tablet broke), I'd definitely buy this Daylight Computer.
Hopefully the company that makes this is successful and continues to expand and support the device. That's the other issue with the Boox tablet; I read on Reddit that there will not be new Android versions for it because the company is part of a culture of moving on to new hardware and abandoning support for deployed hardware quickly.
