People better get used to this now and stop banning it everywhere. What happens when they have this tech in contact lenses? They are working on it. Should be ready in the next 20 years, and that is a very generous time frame.
I hope nobody finds this insensitive posting at this moment, but going forward I hope this type of technology can help the authorities figure out exactly what happened in a terrorist attack and catch these lunatics much quicker.
I cant see anybody paying over €300 for these, and even at that price only the die hard fans will purchase them. I would probably shell out €200 for a pair, if they work as good as they have been advertised.
