They say significantly less contrast, but at the same time they mention it is really only noticable if you hold the glow light model next to the regular model, but then you can't "unsee" the lower contrast. At least based on their web pictures, it looks like about 20% lower contrast.
Not good, but not the end of the world. I think I'll prefer my current one though until the eink tech improves more, so the reduce contrast is at least made up for by the better screen.
As a note, the screen lighting that whatever company it was was talking about a couple of months ago supposedly does NOT reduce contrast at all even though it is a layer over the whole screen. It also seems like you wouldn't need an anti-glare coating as it works on a light guide principal to evenly illuminate the entire display, unlike B&Ns glowlight tech, which is single edge lit, where the anti glare coating would be needed.
So if B&N, or Amazon or whomever adopts this other lighting system, there may be no reduction in contrast (or there might be, total speculation).
At any rate, I hope improved eInk displays are coming soon, and not just a wave of lighted models.
