come on NYTimes, update the iOS app for iPad Pro --- it currently is gigantic (I presume because the screen design is just a scaled-up version of the iPad Air)
It is a valid concern and an excellent bookmark to their original challenge with multiple browsers. Today people read the web on phones from 4" diagonal to tablets 12" to laptops 12" to desktops 37". And designing something which is consumed comfortably across that range is not a trivial task.
