1) The Build Quality is AMAZING, it feels sturdy and it does not feel like it would be too easy to break. (although some have)
2) The screen does not really cause much eye strain, in fact my computer monitor causes more strain on my eyes then Glass.
3) People seem to either not care or are normally accepting with glass. I have not had anyone say anything bad or asked me to take them off.
4) The battery life is terrible, especially if you let a room full of people spend a few minutes to play around with them.

It is still nowhere as bright as my computer monitors.
