A 6.7 inch E-Ink display that pairs with your smartphone

This could be quite interesting! Since the normal display usually takes most of the battery, thus as a person who reads a lot on my phone, having a more battery conserving and eye friendly option when reading could be really cool! But when I would need colour and full functionality I would still have the phone. The only real question now is the price, because I paid ~220€ for my phone, so if it costs equal or more, I don't think I could afford it - to basically buy another phone, but with less functionality...

I have been looking at E-Ink phones, which look quite interesting, would love to try one!

Nice, but make a flexible version I can wrap around my arm. That'd really be handy, not needing to grab the phone all the time but still having a full featured touchscreen on my arm.

that would be awesome so i can get rid of kindle and not need a PC to load 3rd party books

I've been wanting something like this for a long time
