We might be the last two people in the US without cellphones, but we do OK without them. The ipad, however, does come in handy for city navigation, and nowhere as essential as in Anaheim, where we have three key destinations and we'll be bumping around among them.
So here I am in heavy traffic routing us from the RV storage place to tonight's campground near Disney and ultimately to the Fullerton (LA) Amtrak station.
It's a beautiful thing.
I don't care for it to navigate larger distances, where seeing the lay of the land is vital, and I have paper maps galore for that. But with the 3G connection/GPS, the ipad was indispensable for city streets.
