I think so, yes. If PW wasn`t advertised as "perfect" but just "(probably much) better than a book-light", people would know what to expect (and probably many wouldn`t buy it, lol, hence the advertising part...

).
I`m currently in process of trying to convince myself that is shouldn`t be "perfectly white and even" in the first place

, but just a better solution than using (carrying) a book light.
Now, some may find the "coldness" of the led lights (bluish white) distracting and may prefer the yellowish light of the "regular" bulbs, but that`s how it is at the moment. Kindle Paper
yellow, anyone?

I might like to see that, but doubt it`s gonna happen.
