This is the iTard / iSheep syndrome spreading, as if making everything w/ a touchscreen would somehow make it better or faster or easier to operate. A solution looking for a problem. But then again, the target market seems to be the same ones who can't operate any electronic gadget with more than one hardware button... Lulz.
Camcorders have used touch screens for many years, I like them better for large fingers than miniscule buttons, but Its fine if you prefer one or the other.
I expect that the feature could be disabled, just like video, you will not be forced to use it. Thats the case with existing touch screen cameras.
