It's a humanware product, it's major function is a cute blue tooth
connected GPS system.  CPU, sattelite RX, and speaker.
For a bit more, you get a screen reader for windows CE
programs.  Their is a lot I don't know about like, connecting to a
network, the internet, a printer, and or a braille embosser.  Does it
use active Sync?  How rugged is it?  I saw reviews of the other three
pda products in access world; but nothing on the trekker, or that
optilec option.  I am thinking of just waiting a year, because the
PDA options seem to be in a period of rapid change; and see how it
all falls out.  We are talking about the best money in the world, MINE!!!!!
