Amazon Instant Video, a great tool for learning

Amazon Instant Video has found its place in my home educating.  I love the New Dimension shows that pop up when I do a subject search such as "plate tectonics" The New Dimension shows are usually short 7-30 minutes with great educational value.  National Geographic, Discover, Animal Planet and other "hits" I have made in subject searches.  I love that I can stop reading and explaining for a few minutes while relaxing on the couch.  My kids love it because, duh, its TV.  Even better than Amazon instant video is Amazon instant video with my Roku 3.  I can find the programs online or in a search and save them to my watchlist where they will magically appear in my watchlist on my Roku 3 player.
