Coming from Cyberpunk and Shadowrun (no, they aren't FL servers) it was always evident to me. You know, real Sol-fans even have the flatvid version of movies, than the various 3d holoprojection stuff came, and than the neural-technologies. Maybe you grandfather had an ugly interface like we saw on matrix. And here's an early version of the implanless holotain, from before it became so comfy as we know it now. By the way, holotainment's name is misleading, I propose to rename those to neural-tain. :)
