And it might be that denying me coffee in the morning has severe
security repercussions. This hypothetical passenger with ill intent
would obey a "no gps" ban because...?

Not all gpses look like gpses. The globalsat ND100 looks like just
another thumb drive, lots of people have hacked a gps into netbooks.
Data loggers are featureless little blocks that fit neatly into a
shirt pocket.

I've seen a few people fiddling about with their personal
communicators on approach, and even more people playing with their
personal media players; it seems very unlikely that someone with
actual intent to do harm (rather than simple selfishness) would give
any consideration to a restriction on gps - aside from wondering when
the flight attendants will make their final cabin walk-through.

(who'd rather see that cellphones be banned on aircraft because we
don't want to be stuck in a can for a couple of hours with people
blabbering loudly.)

GDB has a 'break' feature; why doesn't it have 'fix' too?
