I agree that the layout of Panel Memory buttons etc. on the KN6000/6500 was better but I guess that was part of the trade off in having a hinged top which gives you better protection for transport etc. I tend to use a footswitch to increment panel memories as well as for other programmed changes.
Apart from the SD card the other features of the 7000 which I particularly appreciate are the organ voices, 128 note polyphony, and the USB interface.
Incidentally for file manipulation on the SD card, Fred Mellink's SD explorer is well worth the money.
