Don't forget a lot of cell phones now have a GPS chip in them to meet E911
requirements. There are tons more cell phones than boaters and campers.

There are orders of magnitude more personal boats cruising the world than
GA
planes, and a significant percentage of those boats have at least one
GPS...
They are the driving force behind the moving map stuff... The millions of
campers, hikers, etc., buy tens of thousands of the under $300 handhelds,
and they are the financial base upon which the GPS moving map industry
sits,
currently... Us high end Moving Map / IFR Approach / WAAS airplane guys
are
the tip of the commercial GPS iceberg...
