I spotted this in June, but have not seen another one since. At 61st Street and Grand Avenue in Queens the printed schedule was replaced with a tablet screen showing expected arrival times. There was some discussion about how going paperless for this was not necessarily a good thing. If this is the paperless solution I do not have a problem with it, though the potential for vandalism is obvious.
