I have had a pilots atlas since 2005.
When its a windy, foggy day and you are struggling to find your enroute alternates at planning stage in the Crewroom, how do you know which runway in Santiago is Cat III. Does Bordeaux have a Cat III approach? Is Nantes ILS to both ends? How do you find this out easily? You may know some of these answers off the top of your head, but I'm sure you don't know them all.
We don't have paper plates in Crewroom anymore, so this is a perfect aid to help planning.
Sorry to disagree. But why carry a pilots atlas in addition to your iPad which has the Maps4Pilots app on it.
