Slightly smaller than the actual paper chart, Garmin's FliteCharts are still easy to see and work with.
Selecting approaches is easy, though you won't get all the waypoints you're looking for.
Who needs en route charts? The IFR map gives you clearly marked high and low airways, with MEAs, distances between fixes and more.
