Touch Screen, as it is natural for any animal (Humans are part of the animal kingdom) to touch what they see, and not look elsewhere to get what they want.
There is also no reason why you can’t have buttons and a touch screen in tandem, so that you can make your own choice. (The Tyros is a good point here, as adding touch to the screen would not mean having to remove the buttons)

I am with you bill.... I am all for a good combination of buttons and touchscreen... And to give Dony a thumbs up, while sliders seem to work okay on a touchscreen, i prefer the real thing, while knobs dont work on a touchscreen at all.. Just give me real knobs..
The knobs we use all the time, need to be on exactly the same position for easy reference, they also need to be tactile, so when playing live you can find them blindly.
I use touch screens a lot...iPad, iPhone etc. As I wrote this on my iPad, I had to use extra care not to touch wrong keys etc, as there is no reference point. So I don't find touch screens all that easy either.
And now try this typing on an aranger witouth touchscreen? Now this is one of the strong points from touchscreens, because tehre is no room for a qwerty keyboard on our arrangers having this on a touchscreen is a godsgift..
And this goes for all those controll and eddit tools you want aboard but there is no room for on the surface of the keyboard/arranger.. Also touch screens are great for making things visuall..
Another good example is when you are playing a drawbar organ, you could have the organ drawbars on the real sliders while still having a touchscreen for accessing the volumes of the different style parts(mixer) and more like thos things..
Also when edditing things, its great to have a pianoroll with touchcontroll while edditing a track instead of a page with numbers
And with current touchscreen prices, its a nobrainer for most developers, you can buy inustrial (thats just the screen witouth box ) 12" full HD touchscreens for far under a hundred dollars with a quallity that you dont need to lift the screen anymore to have good sight on it.
