I agree. If you're happy with your K4NT, this is just a very slight refinement. If you've got a few bucks burning a hole in your pocket, you'll be happy with the new one and can gift your old one away (mine is going to my wife).
I have a Paperwhite on order and I have a feeling that one will blow people away.
