You know, Glacier Girl basically has the original instruments plus a VFR GPS and that's it. You want to chalk that up as an attempt to make the overall aircraft a "restoration", that's fine with me. When you have Steve Hinton at the controls every flight, that's almost as good as state-of-the-art avionics.
But, multi-function displays and their ever-expanding capabilities are revolutionizing general aviation and making flight much safer. I've pretty much told myself that I'm not getting my instrument ticket until I know I'm flying behind those types of avionics. I'm the ultimate purist when it comes to some things, but if it assists with safety of flight, I'll take the most up to date stuff you can install, regardless. New systems save weight, reduce the load on the electrical system, and provide more capability--win-win in my book. If I owned one of those aircraft, it would have a historical paint job but a state of the art avionics package, complete with a more ergonomically designed panel.
