Why exactly a 30 day rotation schedule? To me it puts a lot of pressure on the subscriber to view a particular movie within that timeframe. Sometimes you're too busy or on vacation and you don't have enough time to view all the movies you're interested in. How about a hybrid model that combines the 30 day streaming service with a 3 month VOD service? Or a plus version of the regular subscription that offers a 90 day window for a slightly higher monthly fee?

On Android you can download a movie and view it offline for 7 days. What are the obstacles to offer something similar on other platforms?
