There are three types of complaints I've seen about Glass: * Camera-based privacy concerns. * A rude distraction in my face/someone else's face that interrupts human interaction. * It's ugly. I completely ignore the last. For the second, social norms will change or develop to address this. I expect people who pause in a conversation to stare at their eyeball screen will get similar reactions as people who glance down at their phone. Some will care; some won't. A lot of younger people won't give two poops. For the privacy/camera based concerns, I'm quite fatalistic about it. Google has indicated that it's going to be obvious when you take a picture -- but more importantly, we are going to be surrounded by more and more cameras and sensors as time goes on. Since I don't think we can beat 'em..
