Last week I received word from Amazon that they are now allowing their "Amazon Instant Video" on the iPad. A quick search of the App Store got me the app and upon opening it, I was pleased to see (as an Amazon Prime Member) a complete listing of the videos available to me.
I can watch, pause, and then watch again on the iPad or any other device that has net access and can get to my account. This is all done through Amazon Whispersync, which as what powers the "any device" reading of the Kindle & Kindle Appps.
Needless to say, downtime may now be a ting of the past. The Amazon library has movies as well as aTV shows and boasts over 120,000 tittles!
