One idea that’s been bouncing around in my head for the last few years has been a laptop with an E-Ink display. I would have thought this would be a niche that had been carved out already, but it doesn’t seem that any companies are interested in exploring it.
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.
