I talked to my dealer, and she said that, with the price of the new KN7000 and the changes made from the KN6500, it would not be worthwhile upgrading from the KN6500. I, too, like my KN6500. It has more capabilities than I can figure out how to use. I put a hard drive in it, and it now has everything I need and more. Most people buy new keyboards and never use half of the stuff it comes with. I would say that, if you're happy with the KN6500, stay with it. I am.
