If your hobby and interests are computers and electronic gadgets, then
these systems are probably fascinating - but you really need two
pilots, one to stare at the gadgets and the other to look outside and
fly the airplane... But, if you actually fly for the love of aviating
they add little to nothing to your trip(s) and will cost significant
amounts of money to buy and to operate... The clutter in the cockpit
will be considerable with power cords/data cords to the screen, GPS,
etc...

In a few days we will air tour from Michigan to New Orleans, the gulf
coast of Florida down to Key West, then back up the atlantic coast to
the Carolinas and back to Michigan - in excess of 3000 air miles...
Weather briefings will had from Flight Service... Primary nav will be
Howie Keefe's Air Chart and MK-I eyeballs... Secondary nav will be
VOR/DME and 196/195 for avoiding restricted airspace; and if IFR/IMC is
encountered...... Works for me...
