What I mean is that if the Yamaha and the Korg were the same price and weight - no one would pick the PA80 over the PSR9000. The advantages become obvious because of the overall value and portability, but the features on the Yammy put it ahead of the Korg in most other areas. Subjective? Of course. My needs have YET to be met, so - I'm still looking. Good luck in your search.
