Why so negative?
All GPSs can be turned off if you want to ! You could even throw away your maps, to get the real adventure. And throw away your compas and take a sextant ;o))
Maps,compass and GPS are all means of navigation, you only have to decide how good a navigation you want:
1:100.000 maps or 1:20.000 ?
A big compass with compensation or a small compass on your watchband or a sextant?
30 papermaps or 2-3 overviewmaps and a GPS ?
You can buy extra gas for the GPS money, but then you could also save gas by using the GPS.
You could buy the GPS for the money saved on maps.
You will really appreciateit, that dark evening at 9pm in the rain, when it shows you the way to the next lodge
) or when you find that little single track that'll take you into to the bush faraway from the mainroad(and hopefully back again)
May you enjoy peace and good health !
