Depends on what part you focus on, it's an RLCD so it isn't based on e-Ink tech. Like an e-Ink though, it can be used in direct sunlight since it just uses ambient light. (Maybe it'll have a backlight like the Kindle Paperwhites)
I think the use case is similar enough to a color e-Ink devices.
Thank you for the clarification, I wasn't able to tell from the link if it was backlit or used ambient light.
It's funny to me that they skipped over that feature, but instead talked ones that few of us here probably care about (like thickness). Just another reminder that HN is a far from average sampling of the world.
