In my view, one thing about any wearable device is that people form an impression of what you're doing with it. That's what makes it socially acceptable or not in the long run.
Earphones / buds / blueteeth don't have unlimited social acceptance. If you're talking to me while wearing headphones, I might ask you to take them off, especially if you're one of my kids. If I see you wearing them while while careening towards me on your bike, I might dive for cover. If I see someone wearing them while communing with nature, I might think they're weird.
If any prediction is possible, I'd guess that Google Glasses will also gain some sort of conditional social acceptance based on what they are capable of being used for.
