As someone that's been on the Kindle since the 1st gen, I love the march to something cheap and light/small enough to be held in one hand.
It's just a shame that there's no text-to-speech, which would be really killer on this, the lightest model in the lineup. I find TTS really useful, especially for non-fiction, essays and news (conveying the nuances of fiction, particularly dialogue, can be awkward with TTS). I think the feature's been buried by way of being awkwardly placed in the text-size menu of previous Kindles. I'd say %90 of Kindle owners I talk to have never used it or don't know the functionality is even there.
At the very least, I hope Amazon puts it in their iOS/Android apps.
