I have owned both a Sony PRS-600 and a Kindle 3. I got the Kindle because I was more impressed with the e-ink on non-touch screen devices at the time.
I am really glad that I switched because I do think the screen on the Kindle is much better, but there is something that I miss.
On my Sony, with ePub books, there were chapter marks, which I really liked. In particular I remember my Sony version of Sense and Sensibility had boxes around the chapter numbers. It looked like this:

I guess my question is, is there a way to get this on Kindle ebooks? Or will Kindle ever have this? Now that a nook or sony will have the same clear screen this may be a deal breaker for me.
