Totally different technology. Transflective LCD, which has response rates of 480 Hz or better (as LCD television displays).

Best eInk refresh rates are in the several-Hz range, and that with a tremendous degredation in image quality over a full-refresh.

(I've own an Onyx BOOX Max Lumi for 4+ years now, using an eInk Mobius Carta display (2,200 x 1,650 207 ppi). I'm quite happy with it, but I'm also well aware of its display limitations. For reasonably static text it is indeed excellent.)
