Query: Stay away from UltraViolet Digital Copy

The point of buying the movie with a digital copy is so I can take the movie with my on my iPad and iPhone on a business trip and watch while on a plane or train, or at a hotel with the typical miserable Wifi connection. This UltraViolet Digital Copy / Flixster crap does not allow me to do that, so it's useless, don't buy.
