The article touched on smartphones, but I think missed a point - a huge part of the recent &quot;acceptability&quot; of public transport is that people have got something to do during their trip. In fact I kind of get the feeling people almost welcome bus&#x2F;train trips now as a chance to get in some uninterrupted &quot;phone time&quot;! Previously, unless you brought a book, riding public transport meant a long look out the window. I think that&#x27;s huge.
