E-ink E-reader screens now have vibrant Colors, first reader by Barnes&Noble 

LCD/LED screens are fast and bright & can do video. Ereader screens are black&white but really quit for the eyes, use little batteries and can be read in sunlight. E-ink.com now has screens which are color, still too slow for video they have vibrant colors. The first reader was introduced by Barnes & Noble. Amazon will follow soon. Long live competition
