in late 1999 Garmin produced one of the first MAPPING GPS units. Street Pilot Mark I. black and white. pre-loaded basemaps. $800 or so. street price (yar) was a bit more reasonable, but still, $550 was a tough nut to swallow. then add in the fact that if you wanted street level maps, you drop another $300. oh, and you needed a way to strore those - proprietary memory cards, $200. oops. yah. oh, and it DID not automatically route, or re-route.
bought one anyway. wow. amazing.
now? $250 or so will buy you a top of the line model, with everything... lifetime maptupdate, live traffic, myriad features too notable and important to list.
$25 will get you a serviceable model. cell-phones have it. io6 will come with a very good one in software soon (based on TomTom stuff iirc). hell, i've trashed picked the damn things. they built GPS into anything these days.
and the govt could turn that off anytime they want.
right when you need it the most...
good thing there's other services floating up there. like the chinese

heh.
(oh, and osama/saddam jokes got kinda sad when it was revealed that the USA trained them, then blamed them, burned them, and murdered all their families/etc, and treated their bodies disrespectfully, think about that)
