@foone did you ever see the YotaPhone? It was a normal Android mobile on one side, but if you flipped it over the screen would mirror onto a very fast e-ink display.
@th@foone check out the Boox Palma. It's basically an e-ink PDA... or a e-ink smartphone without a phone modem? Not sure but I wish it had a modem in it :( it's just so cute https://shop.boox.com/products/palma
@th @foone I still regret cancelling my YotaPhone order when the company said it wouldn't work in the US.
