I'm not part of the "All DRM is always bad. No exceptions" consensus group. I'm in the more pragmatic "I'm OK with DRM, especially for time-limited rentals when it works well and is really cheap" group.
Yep, i like both the amazon and itunes rental options for movies. Most movies are a one time deal anyway, and they are FAR cheaper than going to a theater for "meh" movies.
For buying I would like the drm to go bye-bye. They can watermark it for all I care, as long as its a plain file with no drm is what I want for the purchase price so I can move it about like the songs I buy from amazon/itunes. That is basically my viewpoint as well.
Can't we all just get along?
