In essence, this is correct.  After listening to a presentation given
by the market development manager of HumanWare Canada, Sam Adler, I
have a much greater appreciation of the differences between these
models.  And the map-based Sendero model actually is not bad.  It's a
solution I probably will be going with in a few weeks, coupled with
Human
Ware's Trekker device.  If you're basing your GPS tracking on a set of
static maps, then you have the ability to plan routes and scout an
area offline, quite far from your present location.  So if you're
sitting in your apartment in Boston but know you have to take a trip
to Birmingham, Alabama, you can guide yourself virtually through
Birmingham and plan much of your journey before you go.  The way Sam
described it, the WayFinder model of GPS mapping is dynamic and
continuously updated, but somewhat less stable.  And the maps created
by firms such as Navtech are still quite good, since human beings
actually travel through all areas and create the maps based on what
they see and write down.  I believe a model that is intelligently
designed by human interaction might be a lot more foolproof than a
solution that depends just on moment-to-moment technology.  But as
long as you know what you want and why you picked your given solution,
both WayFinder and Sendero have their place.

Having not had first-hand experience yet, Don, I'm far from an expert.
 You can find more details about how Sendero works, particularly with
HumanWare notetakers, by going to

Also, you could join a special interest group that discusses all
manner of accessible GPS solutions.  The list is housed on the same
platform as the JFW Mailing List and is free to join.  Go to
http://www.freelists.org/list/gps-talkusers.
I'm joining this right now, myself.
