Just lost my Kindle Keyboard 3G, so went to look at the Paperwhite, there's a new one out with double storage and a better light. I got the outgoing one for £40 less. Went for the 3G one as I am always on the move and in hotels, sometimes without Wi-Fi.
As above, I went for the 3G model, so it was £130 or something like that. Amazon had refurbished ones from £136. The non-paperwhite is about £60 new now. Having come from the old keyboard one, the paperwhite takes some getting used to, but is actually pretty good. As I was no-where near filling the last one up, I'm not too bothered about the space and any light is better than no light.
