I suppose I was hoping that the PSR1K and PSR1100 (typo PSR1000) might be one and the same, in a desperate attempt to discover Yamaha finally realizing how beneficial having smart media card support is on the PSR1100 and PSR2100. After all the anticipation & build up I was having, what a big letdown & disappointment!
I'm still quite surprised though, that Yamaha would include smart media card support on their PSR1K, yet not on the PSR2100, PSR1100, or Tyros.
