I am waiting for the time, but probably never will see it as I am too old, when holographic projection devices will become available for home use and are adjustable according to he room size and the whole movie or whatever else will be projected happens right in front of the observer in a three dimensional format. What ever company comes out with such a system will have a goldmine. At first it probably will be prohibitive expensive, just like the first VHS players or flat panel TV, but over time the price will come down.
I prefer the big screen experience.
3D holograms would always have to be tiny for it to be in front of you.
