Plus another one who is happy with his SX900.

Lots of things I like about it:
1.Better on board speakers( I find for rehearsal/practice no need to hook up my Maui 5 or Bose Compact)
2.Touch screen
3.Playlist feature
4.Already mentioned the Bluetooth feature comes in handy for a listen from my iPad or iPhone.

One thing I'd like to see improved with a firmware update is the ability in the Parameter Lock section is to have an option to lock the 2 Assign Control Knobs.
