If anyone says that to somebody about their phone, they're clearly not actually mystified as to why someone would have their phone with them in that context. They're much more likely just annoyed by that person's lack of phone etiquette and wishing they would've left it behind. Which is actually a great parallel with Glass- there are no shortage of people with totally legitimate privacy concerns, etc., but I think much of the driving force behind anti-Glass sentiment is humanity collectively sighing, rolling their eyes, and saying, "can we all agree that this is not going to become a thing? Please? Please don't let this become something that is considered socially acceptable because we really don't want to live in that world." I'm sure we all know people who treat their phone like a pacifier and are always screwing around with it at meetings, social occasions, etc. Do it a little, and that's fine, do it too much and it can quickly become one of the most annoying habits a person can have. Glass, as it is being presented at least, seems like something that would allow That Guy to be even more annoying to deal with, and it would be all the time- not just when he whips out his phone. It might lead to there being many, many more That Guys in the world, and it would grant them the ability to be That Guy 24/7/365.25.
