I would order Kindle PW if it were available in Germany. Having said that I would first want to get it in my hands to judge it.
I have the K3 3G and K4. The K4 is my carry n reader, the K3 is for home reading (with light) and when I travel for longer periods. I never used the text to speech or music or audio book features. I use it for reading only. The the KPW does not have an audio feature is not a negative point to me.
Hope the KPW will be available in Germany around April next year. This way I can get more usage out of my present Kindles.
