I agree he is cool, a character that I like that he really seems to be a robot built to be like a human, He is curios, almost and like a child trying to please it's parent. I kind of thought of him as a mix of Ash and Bishop, I watched Aliens again last night, and I could see how David's actor had taken inspiration from him, though might still have some preference with Bishop, we did get to see more of what David was thinking.
Had not seen that trailer before, I like how it feels like an actual commercial for a computer or the like.
