I agree and disagree DNJ. Sure, technology marches on - but what about true mistakes? What about when companies release products that do not have sufficient documentation? Or have not been tested adequately? What about operating system bugs that we find but manufacturers do not? These things do not get cured by osmosis - they require feedback and interaction. Sure, individuals will have individual needs but if they are not unreasonable needs then it's the manufacturer's responsibility to address them.

Everything I have complained about in this particular thread has been a combination of product oversights and insufficient documentation, and that much has also been acknowledged by Yamaha and they are acting to fix the problems. They wouldn't be if I hadn't provided some motivation.
