The last time I checked, there was only one manufacturer with patents on e-ink tech, all the models on the market use the same screens. Even e-ink is more like a brand, not a technology name Remind me how "you need to google something" became a synonym to "you need to search something."

And from the discussion you posted, I was probably right about the market state at the moment. Damn, what a shame, another monopolized market without real competition.
