A timely topic for me. I visited one of my favourite photography sites just yesterday - cameraless. Instead, I took only a pair of high quality binoculars. Looking at some of my favourite scenes through them, I was struck over and over by just how much we give up by photographing in 2D. One of the oldest photographic tricks we use to previsualize imagery is to inspect the subject with one eye closed.
Soon home 3D displays will be common, the Internet will be 3D and so will much of the media. It's just a matter of time.
I may live to regret my certainty. : )
