The “second-hand smoke” analogy is a good one. I’ve sat next to/behind people playing videogames. They pollute the surrounding environment. It’s annoying. Can’t help being distracted, to some extent.
On the other hand, that’s the *only* time other people’s gadgets have distracted me. I’ll gladly pay that [occasional] price to be able to take electronic notes, Google relevant research/articles, and fire off quick emails to research partners. Cost/benefit vastly outweighs it (for me).
