Reading the title I was excited because I thought someone solved the problem with projecting 3D into fog - but that is not the case. Seems like the media in general want everything to be 3D these days. And if it is not a flat monitor is must be 3D right ? - Interesting display concept but still only 2D as many people already pointed out.

I work for one of the partners in the wearIT@work-project (not on the project but close) and can tell you that this is not about augmenting cubefarms.
If you take a closer look at the project goals you'll see that there are areas of work where computers (Desktop, PDA, Smartphone,etc.) are more hindering than helpful in their current form because you need your hands to work.
When your work consists of typing at the keyboard and pushing mice then there is no need to wear a computer. If you need your hands for other tasks you need a better (no WIMP) interface.
Holding a tablet-PC is mostly no option either - but it totally depends on the task. Thats why there is a lot of interest in investigating this topic every few years. The devices get smaller and faster.
