I thought that too. http://en.wikipedia.org/wiki/Mercator_projection
Which map projections would you choose? A difficult decision: http://en.wikipedia.org/wiki/List_of_map_projections

I'd rather have a gigantic globe (that can also be dismantled for moving or storage) than have a wall map.
Edit: Just discovered that if you prefer a conformal map instead of one with equal area then you end up with the Mercator projection.
And this is just the neatest thing to play with: https://www.jasondavies.com/maps/hammer-retroazimuthal/
It looks like one retroazimuthal variant (the Craig retroazimuthal) is sometimes called the "Mecca projection", so you know which way to kneel at sundown if you're into that sort of thing.
