I tried to follow pixel qi closely, my guess is that they were focused more on the portables market and not getting enough traction in that area. Outside of being sold in the OLPC, they were sold at small volumes on sparkfun as diy panels to install into netbooks and in the nearly failed notion ink tablet, they were also in some ruggedized windows tablets made for industrial/military use.
I'd have to find the old videos with Mary-Lou Jepsen, but before they went out of business it was around when the iPad retina came out and they were focusing on retina screens. As far as the screen itself, while it seemingly had some trans reflective properties it was also doing it on a TN, not IPS, panel, so it had that problem where holding it vertically would introduce that odd gradient across the screen.
Today I'm more curious about clearink which showed up out of nowhere at the society for information display conference this year with a new outdoor readable technology: https://youtu.be/9aEYT79-vuo
