That's the most common complaint about the visaplex, the black wash and 200ms refresh. Also the greyness takes awhile to get used to. As a kindle owner I'd switch to a non backlight technology if it gives me color and options for watching video. The kindle app on the iphone is pretty popular, I couldn't do it, my eyes would get too tired after looking at a laptop all day.
FTA... "We think OLED will work better than other technologies. There's no need for a backlight or a polarizer nor stacks of optical film,"
