Ted, for the most part, Yamaha HAS listened to it's customers, initiated many of the changes those customers requested, and had a large thread entitled "YAMAHA LISTENS" where consumers posted those requests.
When the displays went bad on the PSR-900, Yamaha stepped up to the plate and replaced the defective screens at no charge, even a year or more after the keyboard was out of warranty. When there was a software glitch, they came through with free upgrades and provided lots of user friendly instructions on how to install those upgrades. The list of things they changed that users requested is very extensive. I do not consider myself an influential insiders. However, I have had nothing but good experiences in dealing with Yamaha.
All the best,
Gary
