It ws on the buttom of my back back - I had laptop there, some clothes
and Neo was in the middle of it. I was realy surprised too when I
found out about accuracy of the device.

No, I think at that time there was no GPRS available on Neo (or I
didn't know how to turn it on).

Well, It catches fix after about 1 min if there's clear sky above.

As you can see on the picture accuracy was good - Neo recorded my
exact route - I rode a bike on parking lot, once I drove in a circle,
once I didn't use road and drove on the sidewalk - everything is there
:) I think accuracy is comparable to my Garmin device.
