Imagine that you are getting ready to go camping for the weekend, with no cell or internet and planning a nice, relaxing vacation away from civilization. Just in case it rains, you decide to rent a move to watch on the iPad. The instructions say that you have 30 days to watch the movie, but that once you start, the movie will expire in 24 hours.
Fast forward to the campgrounds. The weather is awesome, so you get setled in, then after all of the setup, dinner and cleanup, you put the kids to sleep and get ready for bed. Your wife suggests watching the movie since you have some quiet time together, so at 9:30 pm, you start the movie... halfway into the movie, you find yourself dozing off, and after a completely exhausting day, you stop the movie and fall asleep.
The next day you have plans to hike along the waterfalls. By the time you get back to camp, it's almost 6 pm. You still haven't had dinner yet, so by the time you finish dinner and get the kids to sleep, it's almost 9 pm.
You turn on the ipad to finish the movie, but an error message impeeds your quiet time. The 24 hours have lapsed, and the movie, that you spent 1/2 hour downloading, has not disappeared from your iPad.
This situation in various settings has happened to me several times and I am going to seriously consider not using this Apple video service in the future. Apple can do better than this. They can clearly see that I did not watch the entire video. They should change this policy to enable viewers to watch their videos in full. If the 24 hour expires, they may not be able to watch the video a 2nd or 3rd time (that I understand), but at least give the viewer a week to watch the video that they rented in the first place!!!
