It is OK with Google Glass, just not all the time - gopros are mainly used by narcissistic adrenaline junkies who want to record themselves doing awesome stuff like jumping out of an airplane. Usually not when walking down the street having a coffee. That would be weird.
I believe its not camera but elite and exclusiveness it created got backfired... (though typically it has worked well for other products launches like gmail etc.)
also 1500$ tag is bit over priced for a tech gadget..
