It's a tradeoff.. use LCDs for the cold and the dark, and e-ink for warm and bright.
And what makes you think the batteries on an LCD won't freeze & shut down? There are temperature guidelines for all devices. The battery on my manual Nikon doesn't work in cold either.
I think you'd be hard pressed to find any device that works at either end of the extreme temperature scale. Cold shuts it down & too hot overheats. I'd rather my devices be too cold and shut down than overheat and have to deal with that. Sort of the same as a car that won't start when it's too cold compared to an overheated car. One is far easier to fix than the other.
