Use it at home, home office (self employed). I carry it everywhere in my handbag mostly in the Apple case. I have a Tenba mini messenger that holds my camera, lenses and Ipad so carried on photo shooting also. We have wifi available it seems everywhere from our DT square to drs. offices, to grocery store, our Home Depot, car repair, libraries, restaurants/cafes/fast food, etc so I'm very happy with wifi only. When we travel we have mobile hot spot/Verizon on Palm Pre Plus phone but usually don't have to use it. I'll reconsider 3/4G when I buy Ipad 3 and ur contract for Palm free mobile hot spot runs out.
