Why am I bored?
Because I've had this for a year and a half already. I'm always looking for new sounds and new features to improve my performances and three years is a long time to wait. Also, Korg is proving to be a very able and talented competition. I think that Yamaha needs to copy some of their features -- and the sooner the better!
As to the people who want the 76 key board, I see no reason for it. There's hardly a single instrument on the Yamaha that sounds good in the fifth octave -- so unless they completely redesign all their sounds, it will sound horrible if they add a sixth. Even the piano isn't great...
