I see a lot of envy fueling the hate. I can't afford a $1500 pair of uber-nerd glasses so I will hate on the select few who can.
Starting with a false premise does not help your argument. I think most people on slashdot CAN afford one if they wanted it. The low adoption rate is showing that there is currently no real utility to the device beyond what you can get with a smart phone, albeit with a lot more flash. Therefor, it is assumed that it is no more than the current Rolex watch or Coach bag.
