Is this the future of arranger keyboards also etc, ......will we go totally computer based with a mini Kb controller thats fits in our pocket or a tablet touch screen KB???

LOL! Sure. You turn up at the gig and everyone's saying, "He's not playing any music, he's too busy playing pocket hockey!"

Hey, we're almost there already,...think about it,
won't be long.. we are the last generation to have
HALF pre Computer & Half post Computer in our lives to reflect on..
