Hell, who knows, we could be in one of these computers right now for all we know ;D

You seem to actually have a care for this so check this out http://www.holografika.com/

I myself am actually working on a sans glasses display with correctly focused scenes so I know it's possible.

It would definately allow for speeding up research and throughput in the theoretical sense. The idea of being able to accurately predict the folding patterns of proteins and other nano-scale particles has many benefits and is simply astounding. We could start designing our own proteins and devices incredibly fast.

However, I think you're also getting a bit too excited. Whilst infinite computing power is great, the limiting factor of many experiments is our lack of understanding. There's only so much computers can do to speed us up in the regard. We still need to collect accurate data before we can enter and create models using these computers. It's why we still use animal testing instead of relying solely on computer models and why so many drugs fail even at the clinical trial stage. Wet work will still limit what we can acheive.

we will have .5 lightspeed drives in the next 40 years... in my life time we could potentially reach another solar system, or at the very least visit pluto.

That is very cool. Very useful for 3D modelling and operating theatres.
Nice for gaming too, although probably a bit overkill. Is it possible to get the focal point working while only rendering the scene from one specific perspective? That should be a lot cheaper for gaming with headtracking.
And I guess also more applicable to 3D cinema, assuming the director wants everyone to see the same thing wherever they sit. Although it would increase the reviewability of movies, let's watch it from the left side this time.
