whats he difference between owning a high value car and changing it every other year and owning a high value keyboard and changing it in every other year for the next moodel ? Younger people do it and there is no cry of ripping them off so why is there this outcry for older obviously quite well off people ?

They purchase the organ /keyboard for the same reasons they buy the expensive car surely ? Simply because they kike the fact that they have the latest equipment.
I go to numerous yamaha demos each year an i see the same faces drooling (not because of their age) just like me over the lastest and greatest keyboards. The only difference between them and me is that they attend with their cheque books. If i had their money i would probably do exactly the same. Just because they are older does not mean that they are being ripped off.
