Well - as I said, I do respect Dick's ethic and skill. noelx77, "Madness", is maybe hyperbole? Intentionally Luddite I think, but put myself into that same (Luddite) category with respect to some modern technology - cellular phones and Twitter and Face Book come to mind.
Architeuthis, I share your snicker wrt the "What if" skeptics. It could just as well be asked What if you make an arithmetic error in the sight reduction, or the calculator you use fails, or what if you drop and misalign the sextant or drop it overboard, or... well there are as many what if on the celestial side of the ledger as the GPS. The answer I suppose is have a backup for either.
At any rate it is an admirable skill and I respect it. I used to do arithmetic with a slide rule - can't remember how it works anymore, always had trouble keeping track of the decimal.
