Hm. They look like stuck pixels.
I am near-sighted, and read without glasses. I'm sure I'd be able to pick up all of those pinholes while reading the first page.
To be honest, I'm seeing the same thing that was happening with the very first LCD-screens about 15 years ago. Many came out of the box with one or more dead (always black), hot (always white) pixels. Later on, they became better, but now sub-pixels where sometimes stuck (the red, green or blue part of a pixel would be always off or on). Now, I hardly ever hear or read about dead or stuck (sub)pixels except in rare cases, as long as you're not going for the extremely el-cheapo LCD's.
For LCD's, there actually was/is a standard:
http://en.wikipedia.org/wiki/ISO_13406-2
"The table below shows the maximum number of allowed defects (per type) per 1 million pixels."
Most LCD-monitors are Class II. This means that an acceptable LCD can have:
2 hot pixels AND 2 dead pixels, AND 5 stuck pixels (which may be grouped by 2).
This is per 1 million pixels. A 1920x1080 LCD-screen has 2.073.600 pixels. This means that you may have 4 hot pixels, AND 4 dead pixels, AND 10 stuck pixels (in groups of 2).
Standard or not, I would *never ever* accept a monitor that just barely meets Class II, whatever the standard says. I've actually never seen a Class I monitor (allowing no defects) in the wild; not even quite expensive ones. (Let's say, a €500 19" EIZO LCD, like mine, in 2007 was still Class II.)
In short: if Amazon wanted to, they could just state that the Paperwhite is allowed to have X pinholes, and if it has less, they don't accept returns, just like LCD-manufacturers do/did. I think it would hurt their sales though.

Maybe some people's expectations are a bit too high, but still, these replies are becoming a bit annoying. Just because you don't see pinholes does not mean they can't be a problem.
Some people have vision like an eagle, and they can see a speck of dust at a distance of a mile. Some people have vision like a mole (like me), who can't see an elephant when they're sitting on it. I CAN'T actually see the difference between a good DVD and a Blu-Ray on a normal viewing distance (and I have a 47 inch TV). All my friends are of the opinion that I'm watching blurry movies, but to me, they're fine. Therefore I don't pay almost twice as much for the BR-disk.
However, I do have the hearing of a bat. (Well, almost.)
That means, I hear almost everything; even dog whistles that are pitched somewhat low. Many people can't hear the things I can pick up, but do you know how much NOISE light bulbs, fluorescent lights, TV's, receivers, refridgerators make?! It's maddening.
Since a few years, LCD-manufacturers are skimping on the backlight. Do you know how many LCD-monitors go like: "zzzzzzzz" or "iiiiiiiii" or "ииииииии" all the time, especially if they're not at full brightness (at which level they'll burn your eyes out)? TV's do it too, but because you normally watch with sound on, it can't be heard; if I'm sitting in front of a computer, I *can* hear the LCD's, if they're using cheapo backlights. I've actually returned 4 of them, trying to replace my current one. That constant buzz or whine turns me mad, while others can't even hear it with their ears on top of the screen.
If you have a hearing like mine, you wouldn't BELIEVE how noisy a "silent" room can be. To me, many computers advertised as "silent" sound like a fracking tornado.
I've actually considered soundproofing my walls to dampen both outside and inside noise, but it's way too expensive.
