Link to a video review that has some close-up shots comparing the PW2 with PW1 in low-light. Video creator, Len Edgerly from Kindle Chronicles, got a review unit from Amazon last week, but somehow I missed seeing the video until now.
Screen looks great with the creamy-looking, warmer-colored light, the elimination of color blobs and no more annoying uneven light along the bottom. I ended up returning my PW1 hoping the next-gen would work out the kinks and from everything I've seen and read it looks like they've done that.
I was waiting to buy the PW2 until I saw some first impressions. With both the dramatic changes to the light and the new Carta E-ink screen (that will likely be state-of-the-art for E-ink readers for the next few years the same way Pearl screens have been for the last 3 years) I'll definitely be getting a PW2 and keeping it.
Also, listening to the
latest episode of the Kindle Chronicles podcast from the creator of that video at the 5:50 mark it mentioned that the light on the PW2 when set to its lowest setting is actually dimmer than the PW1, but still does not turn completely off (someone here had asked about how dim the light goes)
