Jeff has a client who's going to be doing a great American roadtrip with RVs and they want to bring all their tech. They need to sync it all, and Jeff wants to know how they can do that while on the road? Leo says that the Airport Express is a Wi-Fi access spot and it will be a router if he plugs it into the internet primarily. Jeff can create an Ad-Hoc network without Internet access as well.
Leo recommends, however, getting a MiFi. That way he can create a Wi-Fi access point and connect up to five separate devices. The iPhone can even be his network. Then he doesn't really need to buy anything.
