Interesting post! I, too, would be lost without my KN7000. When I had my KN6000, the finish on the buttons wore badly. I think the reason was because the keyboard wasn't covered. It didn't have a built in cover as the KN7000 has. Dust and oil from our fingers causes this problem. I strongly advise those that have not had this problem thus far to make sure your keyboard is dusted regularly and keep those fingers clean. This will keep this problem from happening for a long time. Arranging and editing as much as I do, I have had no problem with this happening on the KN7000. My KB looks brand new.
