The PSR800 was one of the best arrangers Yamaha ever made. The vocal harmonizer was BETTER than the one they have now, at least it sounded better to me.
It only had 2 variations per style, but it was way ahead of everything else on the market at the time. I kept going back to it after I had 740 and then again after the 9000. Many of the sounds are still on the current Yamahas.
You can move the style locations around on it, and it had that really neat Swing feature that allowed you to easily change all the styles and save both versions.
It was probably a matter of his being very comfortable with it, and the T3 being in need of extensive setup and editing. I can relate and understand. I can't see any reason to attack a person personally and question his intelligence or judgment in this case, or any other case actually.
