Came here to see the general opinion about Kindle readers and I agree with majority here.
I wouldn't upgrade my K4 non-touch for the Paperwhite (trying really hard not to type paperweight
) - if I did I think I would miss the page turn buttons.
But on the plus side I am really happy that Amazon is starting to sell them at $69 - that is good value for such a brilliantly useful product. And the paperwhite thing looks lovely - and I can not stop thinking how nice colours would look on such a screen.. so may be that's the next iteration Amazon has in mind? I am perfectly fine with my K4 NT for another year and will see if they release A "PaperColour" Kindle!
