I got my Kindle PW2 four days ago and I wanted to add my two cents:
So far, I've been reading on a Pocketbook Touch Lux. Compared to the Kindle it looks quite slow and grey. I can't believe how bright the Kindle is! I put the two screens next to each other with full lights on and they were worlds apart.
However, my PB has an even distribution of light whereas my Kindle has a shadow on the bottom left and a very bright spot on the bottom right. Reading during the day, it doesn't annoy me as much as I first thought it would. That's why I'm keeping it, escpecially after reading comments about dust under the screens or tilted screens. Luckily, I don't have these problems.
I also love the responsiveness of the Kindle, being able to flip through pages with a preview and the footnotes pop-ups.
Still, I'm taking my Pocketbook to bed with me. Simple reason: It shows the time in the status bar. Plus, it shows much more text on a single page, not having such wide margins as the Kindle. That's much more convenient for me when reading in bed.
Another thing which could be better about the Kindle is the font size. The few serif fonts I like are either shown as a bit too small or a bit too big. And what about crashing on PDF files? That's really disappointing for such a high-end device.
But on the whole it's really beautiful and I already love it.
