Agreed.
The SX900 is a great kb and fun to play and experiment with. But I don't feel comfortable taking it out on a job. The touch screen is fine for my home playing, but different enough from previous models I can't get where I need to go as quickly as using the buttons. The process of creating registration banks and registrations also seems more complicated than on previous models. Maybe I will gig with it in the future, but for now the S970 travels with me.
