I messed with it as well, but I think there's a lot of inflated importance on page turning speed and it's probably fixable with a software rev either way. I've never been able to turn book pages much faster and it never hindered my reading pleasure. I think they need to focus on the menu system a little more. It's good, but could use some improvements.
I had a gen 1 Kindle, and sold it because I was frustrated with the page turning rate. Well, not just the page turning rate. It was that, combined with a smaller screen area, combined with a lower-contrast display (than paper), which made me increase the text size over paper books. Combined, it meant that I spent a whole lot of time looking at the flickering refresh, and not reading words.
I really wanted to like the Kindle, and I think that one or two more revs and It'll be something I want to use.
