This is kind of disappointing. I broke the screen on my Kindle 3 the other day, but wasn't too worried because I was planning on getting either this Kindle or the Touch anyways. I was thinking of buying the $79 Kindle today, since I didn't want to stop reading on the go for a month (I really don't like LCD screens) while waiting for the Touch to come out, but now I'm definitely rethinking it, especially due to the ghosting - sounds like it would get very annoying.
I've read two books so far on the ad-free version of this Kindle, and I've seen the degraded quality when I study the page quality, but never while actually reading.
