I had opportunity to buy a Kindle Paperwhite and I was looking for an equivalent which support colors. Amazon have the Kindle Fire but it is a tablet technology which is not comparable to the e-ink.
The reader with e-Ink are (for my usage) superior for the battery life (several weeks without charging) and for the readability under bright place (sunny).
My question is: do you know any device with color e-ink, and if it does not, do you have proof that it can be real one day?
I hope my question is not too opinion centric, I am looking for facts not opinions.
