I don't consider anything digital as being bought unless I own it free and clear, unencumbered of any encryption. Not interested in anyone's "digital locker" or storage scheme. I have 20 years of music bought digitally through iTunes and Amazon. I can still play them to this day without needing to check-in with a licensing server. That is ownership. That is why I don't buy encrypted movies.

I think Heinlein said, "You do not truly own anything that you can't carry in both arms at a dead run."

I think something similar applies to digital media - you don't truly own anything that's not stored in bits on a hard drive that you can pick up and put in your pocket.
