Ah, the Aximiser... Seen that thread.
Wasn't sure if his USB Host card would work with a 3G card though, hence the question! The card needs to be powered from USB...
Failing that, a 3G CF card?
I'm liking the suggestion on the case front... How securely does the ally case hold a standard batteried axim?
I'll check the GPS software out (and get a GPS adapter obviously!!!).
