Looks promising.

I wonder though how it is for people with glasses (like me). The frame so far seem to have no special feature to allow wearing them. Also, big differences in dioptries can prevent you from using stereoscopic images, because the size differences of the images in each eye become too big as if the brain could match them anymore.

Dslyecxi posted a hands-on video of it a while back:

Ah, I missed the part on that there is only one display for both eyes. I believed it is two different minidisplays for both eyes, with greater resolution.
