the vast majority of these Keyboards are designed for the amateur market, are purchased by the amateur market and marketed to the amateur market. Pro sales make up a tiny percentage of the overall sales. In the amateur market, the weight of the keyboard is not going to be as much of an issue as it would be to the pro market as for the most part the keyboard will sit in the living room for personal entertainment and not gigging use. You cannot seriously expect the keyboard manufacturers to gear their whole marketing proposition to the pro sales when they make so much more from the amateur market .

I own the PA1X and am not in either the pro or fully amateur camp. Its one of the heaviest arrangers on the market. Do i like the weight ? Hell no! Its like going to the gym just carrying it from the car to church. Do i like its functionality , sound, immediate playability (worths latest new word), recordability, flexibility etc etc YES !!! Despite the weight i purchased the board as the features were more useful to me. Many of the pros, even on this board will sue a fraction of the functions on the keyboard to make a good living. Samplers and sound editors and to some extent even fully blown sequencers may not be of benefit to them. But they are to users like me. If the manufatcturers were to heed many of the pros comments , then all they would need is a lightweight controller keyboard and a band in a box type module. But the manufacturers would be bankrupt in a year as this clearly is not what the market that makes themthe most money wants and i for one am grateful for that.
