We used an entry-level iPad with the Verizon 3G Mifi on our 11,000 mile road trip last summer, and all went smoothly (it came in particularly handy when the car's onboard GPS system* went berserk during a thunderstorm in Alexandria VA and kept sending us onto an airport service road instead of to our motel). As I've probably mentioned, I use the device principally to avoid having to deal with BDS' sippy-cup data pipeline and idiotic, arbitrary firewalls, but it has come in very handy as a mobile access device times past.

cordially,

*The GPS unit was operating on its original data set, and was accordingly eight years behind on its geography. It tried to take us through the Cardinals' new ballpark in St. Louis. A major highway in North Carolina had been re-routed; GPS took this to mean that we were barreling across plowed fields, or that perhaps it had been stolen and installed in a tractor, and pleaded piteously for us to reconsider. We took to calling the device "Eleanor," short for Elevated anxiety, not on route.
