The aliasing that I saw was kind of weird, could have been the earlier hardware or the software demo that was running on it. The "pixels" that were visible was not a regular grid of squares. They looked like a tessalating pattern, where each pixel in the image had a shape that looked like several smaller rectangles glued together. The overall effect was like looking at a textile "mesh" or a screendoor close up.
The other unit that I played with was a newer chinese unit (I forget the brand name). It had integrated eye tracking and more sophisticated software. In that unit the image just looked chunky - i.e. A regular pixel grid that was slightly out of focus. The effect was similar to rendering a lo-res image and upscaling it through a bicubic filter, although I guess the blurring was from a physical part of the system rather than a filtering step.
I'm looking forward to trying out the consumer units to see how they look.
