EUGENE:
Your comment that usable GPS has been in every phone for years is simply not accurate.

To get what you say you want, today, you need to purchase one of the new unlocked high CPU smartphones or PDA's that have a quality GPS receiver built-in, plus a 2/4 gig memory card, usually plus the (correct for your purpose & area) mapping software...or put all this together yourself. In any case to get a top preforming unit you need to be prepared to spend from $700 to $1000. That my friend is why the Verizon unit is such a wonderful tool and bargin for the average Joe.
