Can somebody who is lost...
...also be uncertain of their postion, or is lost a position?
Banter aside, I would recommend learning to use the GPS well before relying on it. In my relatively early days (still really early days to be honest!) I flew up with a little GPS and didn't really understand the difference between course deviation and bearing pointer. I knew where my waypoing was, by a function of the M1, but it was disconcerting apparently to have the GPS pointing in an entirely random, but fixed direction with some bar breaking in the middle. Hey ho, you navigate, you fly, you land, and you are glad to get the door open to allow the smell to go away...
These days, I have an excellent little HP Travel Companion (cheap as chips these days with Tomtom cornering the Road GPS Market). Built in gps; red spot on where you are and I don't think it makes me a bad person. I do enjoy my fling more, knowing it's there.
