Film companies have used PocketPCs to replace huge, complicated hydrolic computer programmed camera lifts. These things record the angle and such of a film level camera and replay the exact motion over again.
It can connect to WiFi Networks, bluetooth devices, GPS as you said... there are tons of other very fascinating things that they're capable of... but I've forgotten at the moment.
This is what I wanted to know, Presto your information is a help but I knew most of that stuff anyway. I find it hard to find information on this stuff.
Thanks
