Number One: paper charts are not obsolete, at the contrary, and I advice everybody to train in usage - and do it north up. For flying and keeping your intuition for orientation in space there is none better.
Number Two: a lot of brain laziness is produced by moving maps, but there definitely is one benefit for electronic charts - for operating an aircraft. I emphasize that way because there is a big difference between manual piloting an aircraft and let do electronics operating an aircraft. Using all the electronic gadgets, being able to push buttons, configure irritating track up moving maps is not airmenship in my eyes, it is simple computer systems operations.
I do prefer to fly an aircraft, but I am an old fart and enjoy even planes that old they even don't have any electricity.
