Regarding the difference in the perception of whiteness or blackness in different units.

I have had several opportunities to compare my trusty PocketBook 360, with second generation display to Kindle 3 with the latest "pearl" screen.

1. The difference varies with displayed content. When you compare picture (especially "screensaver") on Kindle 3 to text on PB360 the difference is striking. Text to text isn't *that* different.

2 The difference even more markedly varies with the ambient light. I have been comparing them in direct sunlight, indoors during the day, under incandescent light, under fluorescent lights, under mixed lightning conditions. Under artificial light, in conditions I do 90% of my reading in, the difference is minimal.

And, mind you, I am talking about "good old" (TM) PocketBook 360 and not about the "new and improved" version of Vizplex display that 602 ... 903 have.

I do not claim that Pearl display is not better, I merely want to point out that conflicting reports regarding the difference between various units might be due to different lightning conditions. And do not get me started on the topic of various cameras.
When the very first e-ink devices came out, all we had were photos made by professional photographers under very favorable conditions. Many people, when they received the first units said that the screens are "too photogenic" ;-)
