I use my laptop in some non-traditional environments, such as outdoors in direct sunlight. Almost all laptops are abysmal in a scenario like this. E-Ink screens are a natural response to this requirement. Unlike traditional TFT-LCD screens, E-Ink panels are meant to be viewed with an abundance of natural light. As a human, I too enjoy natural light. Besides my fantasies of hacking on the beach, these would be very useful to combat the raster burn that seems to be so common among regular computer users.
