I think (please correct me if I’m wrong) you’re just bumping on the term “plugged in”. If there was a small shelf of books and short stories I get the sense you’d react differently. It’s just that, in 2017, a dedicated wifi network with some books on it is exactly the same as a shelf.
I live in Boston, and I see people reading on the T every day. I love seeing people reading. This encourages more people to do so. I’m in favor.
