According to the superlative "The March Up" (by Bing West), the
marines in Iraq actually preferred the commercial GPS units to the
military variety.

Not in that book, but probably on TV or in the WSJ, I recall that one

I'll take a look at the book, Dan.
I was directing my comments at aircraft electronics though.
Handheld GPS isn't aviation. (not purposely anyway)
