Why would it matter where he lives? He has no wi-fi at his house?
Myself, I can't get any 3G connection at my home. Fortunately, that is about the only place in the world where I really don't have any need for a 3G connection and I absolutely don't care.
But there are probably lots of people who fall for all the marketing BS. Here in England, first they sold you "wireless broadband". And people bought it thinking it is somehow better than "wired broadband" - not realising that it is still broadband coming into your home through the phone cable, and the whole difference was that it was a wireless router instead of wired router using Ethernet. People have crawled under their desks to remove ethernet cables from computers in their office, standing in a fixed location two meters from their router, using slower WiFi instead.
Now they are doing the same with 3G instead of WiFi. So people buy a laptop, with an expensive 3G data plan, using it exclusively at home, even when they have perfectly working WiFi. So they pay more money, have a slower connection, have severely limited data, and they think it is progress because it is 3G instead of WiFi.
Just wondering if anyone has tried this: If you have no wireless router at home, just a Macintosh connected to a wired router through broadband, then "Internet Sharing" should allow an iPad access to the Internet, right?
