Hmmmm ... I don't want to be forced to have carry an iPad and have to poke at that during a live performance. While iPad connectivity sure is a cool feature I don't want it to have to become essential to me performing live with a keyboard.
Nigel I totally agree,....
I don't need no stinkin iPad!!

Just more crap to carry and set up. Just want everything I need "on board" and working correctly for my needs.
