Doug,
As always, your reply was most enjoyable, but there is a huge difference between "thinking" that the keys are shrinking, and actually measuring them. The keys are absolutly, physically smaller (width-wise) than a traditional piano or synth key. Maybe your points about kids is part of their madness, but this is not a question of "my aging hands". Yamaha made the keys smaller, so my original question stands:
WHY?
