Pedro,

The DV920 works even with frame-sequential stereo, but with a native
resolution of 640x480, they aren't useful for real work. Plus, they're
not all that comfortable -- I returned them after a couple of week.

According to the Vuzix rep I spoke to on the phone, we are still years
away from having 1024x768 or better resolution in sub-$1,000 consumer VR
glasses.

Cheers,
Warren
