Mmmmm.... that's an angle I hadn't thought of Brian!
I sort of read it like this: some ponkers from the software industry were telling Scotty that he needs a 3G GPS
Now, given that these legends in Bill Gates' lunchtime have probably never navigated anything more than a paddling pool in a small boat, and that there were copious amounts of alcohol involved in the lead-up to the conversation, suggests that the information may be less than reliable!
Anyway, GPS is a satellite navigation system, 3G is a 3rd Generation mobile communication system operating in the range 300-2000 kilobits per second. Maybe they are confused by GPRS - an interim solution for data transmission at about 50-100kbps over the current digital mobile 'phone network.
Confused? Well, it's certainly not straightforward getting to the root of the matter with some of the marketing surrounding all of this. Here's an interesting GPRS product I came across recently (Yes, GPR
