Well, I just voted for it to go dimmer, though I'm not that bothered, as it's pretty much nearly dim enough on the minimum for me.
However, I just had a play with a Kindle Paperwhite in Waterstones and that has both many more smaller gradations, and goes quite a bit dimmer. I also couldn't fault the display in any way, so have no idea if the fuss about the paperwhite has any bearing on this. It looked good to me. (still prefer the way you use a Kobo though, seems more intuitive to me at least).
