I was thinking of a 3 screen display upgrade this year, but I think I will hold out for a HMD...that Natalia one may be the beginning...
I wear varifocal glasses and using TrackIr, when I look sideways...not ideal.
But with a HMD, no more problems !
Also the Natalia can track your hands with its cameras. That means you could be flipping switches in mid air !
for a real VR experience.
Of course price goes with image size and resolution...but its becoming real, a 75 inch at 10 feet equivalent for $500 seems to be a possibility within a year (optimism is my middle name)
