If you had chosen to buy that movie from Amazon or Google Play instead, you could play it on all of those devices (yes, Google purchases can be watched on iOS devices). Amazon even gives you a WMV file for your Windows Media Player in addition to the streaming rights. The studios didn't force you to choose a more restrictive seller. You can't play a DVD from Wal-Mart on your phone either, but making more choices available to you is not a bad thing.
