Yea, I wouldn't buy one either but I'm definitely excited that this technology is being pursued. I'll wait until the device is built into a normal pair of glasses, impossible to tell the difference between a normal pair or Google Glasses.
I'd want to see legislation that would exactly prevent that sort of thing. The issue with GG is not that it looks geeky, that's just a matter of morphing fashion ideals, but what it means. GG that's even more stealth would be worse than what GG already is. So any sort of "integrated into regular glasses" technology should be mandated to have neon-green frames or something like that, which warns people from half a mile away that some wanna-be-spook with his "I record my life stream video because I can't handle the fact that I'm mortal" device is approaching.
Everyone seems to be brainwashed into this idea that the loss of privacy is "inevitable". That's like brainwashing serfs into the idea that slavery is "inevitable". Everything is inevitable until people decide that it's undesirable enough to make a ruckus about it. It's high time that people start making a ruckus.
