Just an FYI, on the ES7500 I set up, the camera IS able to be moved/angled up and down and side to side without moving the whole tv. The camera is accessible from the back of the TV - it feels like a small rolling ball and is easily movable with a finger flick.
Also set up an ES8K today, but didn't have much of a chance to mess with it. Would not connect to the internet or recognize gestures, although I didn't try for very long before skipping it because I just wanted to see the picture.
