For the sake of every professional (and semi-professional such as myself) photographer out there, I wish, to use your terminology, that the manufacturer's heads remain firmly up their asses. The only thing touching the LCD on my camera is my nose while I look through the viewfinder and when I am looking at the screen it's because I'm holding the camera in a strange position that doesn't allow me to use a touchscreen either. Give me an open API so I can offload all the smarts to my infinitely more capable phone that already has a SIM card with a huge data plan and keep the camera a camera.
