Exactly. There's always a layer of apprehension when buying an accessory device because you know it will always be beholden to either your other computer or some third party service for certain functions. If I needed to, I could use a Surface or even one of the old Bay Trail windows tablets to cut together and burn a DVD for one of my technically-inept relatives. Ipads can't. They couldn't even access generic flash drives until last year.

Any device that can't make its own reinstallation media feels like using a house of cards.
