Daniel, I'm sure you're right, but it's really not needed for the kind of flying I do. I generally don't go much further than 80 miles from home, and the topography of Western Washington not only gives me some good natural Navaids (a set of volcanos), but it tends to funnel me on easily-followed routes. I have a GPS (Garmin hiking unit, cost $100) but only use it two or three flights a year.
It's fun to consider using some of the more-modern electronics, but when I fly, I set the radio to 122.8, the altimeter to 58 feet, and the calendar to 1932.
Though if there's an App that'll project a gunsight reticule to the inside of the windshield, I'd be willing to reconsider. :-)
