Pointless post I guess but a comment just for the heck of it.

I have been spending quite a bit of my keyboard time on my recently purchased DGX 650. I don't have a lot of experience with pianos but I do enjoy 88 keys and a simulated hammer action.

Also, then when I go to my S970, the keyboard feels much more like a toy keyboard.

Maybe this is why some of my piano playing friends don't seem to get too enthused when I suggest playing my S970 just for the fun of it.
