The Question is simple touchscreens, yes or no?

With all brands except Yamaha having adapted to touch screens on one or more models of their arrangers, and even Casio updating their under $1000 piano range with a very nice touchscreen interface. Do you think a touchscreen interface is a win for arrangers?

So would you prefer the touchscreen interface to replace many of the current buttons. cleaning up the surface of the arranger? Or would you like to see the touchscreen only being used for advanced feature, that you dont use all the time, and where there is no more room for buttons on the arranger?
