The price is a rip off, I'm working with these for a client and you
can pick the devices up wholesale for about $70. The gps in them is ok
but all the ones we've tried haven't been as accurate as the gps in my
G1 phone. It is to do with the size of the antenna which has to be
small due to the small form factor.
