Well I don't know about that

We already have working glasses prototypes with displays and motion/distance/color/sound etc etc sensors so Augmented Reality stuff will come first... And virtual objects not only are dirt insensitive, unbreakable, weight nothing, can take any form and defy rules to which even nanotechnology will obey... After such things features shown in this video do not bring that much of and impact.
But still nanotechnology will bring some stuff that is a lot better then this guy ideas. Say colony of nanomachines that live in our mouth and cleans our teeth

Or ones that clean our house living like small insect swarm. Or clothes that change their properties depending on conditions alike to Venom suite from spiderman

But it all shore will take time of at least 10 years if not all 50.
