I'm sure that holoprojections will be a big factor in long-distance communication (when it's too far to visit in person) but I'm not sure it will always replace short-distance personal contact. I figure that when it's someone you don't want to make physical contact with it won't matter, but when you would… you're going to want to have that option. Still, I do wonder if society will change how it values real personal touch over time.
