I've been trying to talk my boss into letting us go to iPads to reduce our paperwork and materials we deal with. (Any given day I have three to five clipboards and a milk crate of reference books.) But are they going to last for us? We played around with Trimble Nomads, but at $1500 a pop and old technology, we didn't get very far with them. So what's your experience using an iPad outdoors in the sun, rain, and weather. Are the cases that are out there enough to protect them? Or are we just going to trash a pile of iPads or be sorry we went that way?
