For simple tasks (someone pointed out a rental car agent doing the walk around photo taking and signature capturing) an iPad is great - its light weight is the main advantage. But if I was doing a walking-around task that was more complex, a convertible laptop that folds around (HP x360 for example) and runs a real OS is just more powerful. There’s nothing an iPad can do (besides being light) that wouldn’t be done better by such a device. (Assume here that Apple made an x360-shaped Mac, this argument isn’t about Windows vs Mac).
