We give a new proof of the fact that every planar graph is 5-choosable, and use it to show that every graph drawn in the plane so that the distance between every pair of crossings is at least 15 is ...5-choosable. At the same time we may allow some vertices to have lists of size four only, as long as they are far apart and far from the crossings.
