To do DOF or not to do DOF?

To do DOF or not to do DOF? I've decided for the last, at least for now. If I've got the physics working, I can imagine a Depth of Field effect which always focuses on the surface the crosshairs point to. Maybe you remember the precipice level in the first Half Life game, where the outlook was a blurred bitmap. I didn't like that. In my opinion it's very unnatural that you can't focus your view on what you want if your avatar is a human being. If you see the world through the cameras of a remotely controlled robot, it's a different thing.

Here is an image of my work desk, if you're interested
