I have spent most of my first 100 dives staring at a tiny LCD screen. Whatever you do, do not make the mistake I made, and stay away from the LCD bacpac.
I prefer using the LCD when on med or narrow mode. I want to ensure that I capture my subject in the frame. I don't always use the LCD especially when I am not really close to my subject. I can see what you mean by fixating oneself to this tiny screen. It does take away from the dive experience, and enjoyment.
I think it is a good point to mention this because there are two sides to this. Its a matter of knowing when to reference the LCD screen to confirm your close up shot.
I sometimes do a quick light and camera check to see if they are lined up in the screen. Once I have checked I really don't bother rechecking and focus on the lit area only. This helps me from focusing to much on the LCD screen, IMO.
