Earlier quoted context omitted.
I think backlit E-ink screens would be great for cars. I too want something I can see well in the day.
E-ink is slow/inefficient to react, so probably not suitable for speedometer and tachometer type gauges. Apart from that, I agree.
(although i've never understood why it has a tach since its a manual anyway... but i guess i can close my eyes and imagine my V6 ranger is a corvette...)
