LCDsHow do they block?
I'm guessing you're under 30?Samsung glasses are wireless and battery powered but weigh no more than my sunglasses, they are really nice.
One problem the makers are facing is that young people are happier with large glasses / bluetooth headsets etc, while older people object to too much 'bling' on their faces.
That's a problem if you are trying to sell $2K TVs to people who already have flat screen TVs.
They can with double rate blue-ray and a sync source.They don't work with regular TV.
Of course whether the makers enable this (standalone syncs etc) has an obvious answer!
