It's not really a scam but rather a technology that's still in its infancy. I think of it more like the Palm Treo and Blackberry: they're not great but hopefully we're progressing towards the iPhone. I wouldn't buy one at the moment, though.
It's a scam as in it costs much more than the B/W displays but has worse specs than it.
E-ink contrast is something like 1:15, it's pretty bad.
*) in the realm of electrophoretic displays or with strong ambient light, not compared to some 2000 nit OLED in the dark
My reference point is physical paper.
You think e-ink has worst contrast than physical paper? How so?
I hold them side by side.
what's the contrast of physical paper in the dark?
We are talking about e-ink without added edge lighting. I found that if I have to crank up the internal lighting of an e-reader to get adequate contrast, then I may as well use a tablet, because it isn’t reflective illumination anymore to the eye.
I have a Dasun Color, it's by far the worst purchase I ever made. Turd.
