About your other people comment, it's a two way street. Other people also get headaches from the obnoxiousness of these devices.

If someone is sitting next to me glancing at my smartphone screen, it's usually not a big deal. But if they might be recording my screen, that's more likely to be a big deal. Even though it can be a mix of perception and reality, I think privacy issues are the root cause of the discomfort with these devices.

This is the kind of headaches I thought were being talked about when I saw the title.
