It is not about forcing one to use a touch screen, but allowing the option. Your "prosumer" argument also fails when you look at the other "craptastic trends" included with the camera -- tilt LCD, auto modes ON THE DIAL, video, that damned autofocus stuff too!!
Not everyone walks around with sweaty or frozen fingers, and when looking at the NEX line, the models without a touch screen are usually dinged for its exclusion because (gasp) they are useful to have.
I don't mind, you mind. That's life. I've never felt the need for a touch screen on my camera, for me they could have excluded the screen entirely.
