Five Likes:

1. Three right hand voices with Voice effects
2. Touch Screen is excellent
3. Chord Looper (Just now experimenting, I can see the possibilities)
4. Playlist. Way better than Music Finder
5. Free Expansion Packs

Five Dislikes:

1. OS Updates, or rather the lack of
2. Style Category. The location of styles has changed too much.
3. Drum Editing, very little can be changed
4. Midi player control. I can't figure out how to quickly rewind to a song, maybe I'm missing something, but no shortcut to the beginning of a song?
5. VH is OK, but no better than OK

All that being said, I love the SX-900
