I can understand why the Boing Boing crew is so anti-DRM and into the copyfight. But realistically, I can get a movie on iTunes for the same price as one ticket in the theater. If they think of iTunes as replacing DVD sales, then yeah, being able to only view downloaded material on particular machines is a total ripoff. But I'm looking at The Italian Job on iTunes. It's ten bucks. Renting it would be what, five? With the rate of inflation these prices are nearly identical. And instead of renting it for a weekend, I get it as long as I keep my computer and the 5 machines I can copy it to. That's a rental period of years.
I think free content will ultimately replace paid content, but in the meantime, this is a good deal.
