In other words, it heavily degrades what otherwise bigger resolution could actually show on the PW screen.

You miss his point, even though you both are really talking about the same thing. This effect is expected to be uncovered when you take such a zoomed in photo of the text when talking about a light guide like this. The Nook has a similar effect as well.
It's a trade-off. To have the built-in light that adds so little bulk, you have to use a light guide. And the light guide's surface will cause refraction. That refraction does two things:
1) Directs the light onto the page to provide the illumination.
2) Causes distortions in the image depending on the exact texture used.

I don't really believe so, the text is still has less aliasing and more well-defined edges, even if they aren't sharp. If the goal here is to replicate print more accurately, the PW does a better job. Is it a revolution in detail? Nope. Ideally we'd get something like a 1600x1200 pixel display at 6" which would be over 300ppi, and even with the light you should get nice sharp text.
At this scale, the eyes are surprisingly forgiving. Take all those LCD monitors where a pixel that we perceive as a single color is really a RGB triplet of subpixels.
But yeah, it isn't tack-sharp... and unfortunately, the physics in the matter say that if we want a light guide over the display, we can't get tack sharp results at such small scales.
