Touch Screen is a MUST ! IMHO

Touchscreen does not contradicts EVF at all - it only widens the operational possibilities .

I have external EVF on my NEX-5n and it is alsways attached. I am shooting mostly using EVF but at some situations, touch screen is extreemly useful.

The EVF has sensors that disable the touch screen when the camera is brought to the eye level - to prevent "nose operations"

I dont think I will ever buy a camera without touch screen
