I think that's going a little too far. Already we've embedded ourselves in a world where many people break open their phone in the middle of a conversation. Yes, it's rude. But it's still a change that's happening in the world. However, Glass isn't always on, at least not right now. You have to manually turn it on, which means it'll be akin to taking out your phone.

But can you see if someone else's Glass is displaying them something or whispering them something? At least with a phone it's obvious.

[easong]

Yes, actually. The screen lights up and it's pretty obvious. Most of the people I talk to while wearing glass notice it immediately when it comes on.

And I seem to remember something about Google requiring all apps to light up the screen, to avoid the whole "stealth" thing.
