Its an immersive display that covers both eyes, its intended to 
completely focus you on the audio and video, for watching movies
on an airplane or moving through a VR world. Its pretty hard to
walk around with both eyes covered.

Most of us do not want immersive displays like those commonly 
used in virtual reality. Instead, we want augmented reality or
mediated reality, where we can see both the computer screen and
our environment. Problem is, the really nice mono displays are 
selling for more than we can afford. So people are modifying 
the cheaper displays to get as close as possible to what we 
want. You can go with mono M1 or Liteye-100, they only cover 
one eye, but they are really just text-based environments 
running at say 15 lines/50 characters text (using SVGATextMode). 
The reason I suggest Cy-Visor is that it can do exactly what 
you can do on a CRT monitor (most importantly run x-windows 
at reasonable resolution). It really depends on what your 
needs for mobility are, and whether you want the immersive 
or augmented modality. Also whether you are willing to rip 
apart the display and modify.

If you wait for HMDs it will be a long wait. There are other
viable mobile displays using small TFT LCD flat panels and 
even smaller text/graphics LCDs. I want them all. They all
have their place. Even if I had a VGA HMD I would still want
to have my 6.4" TFT LCD as an external peripheral. I think 
I would get pretty dizzy wearing a display for 12 hours.

Probably.
