Amazon Fire Tablets offer a neat little feature, to ensure that you always have something to watch, even when disconnected from the internet. It’s called: On Deck.
On Deck will download pilot episodes of Amazon shows, or even Prime Movies (Interstellar just dropped On Deck on my device), so that you can watch it when you get bored.
I don’t think it’s based off your preferences, although it may be influenced by it, but rather it downloads what Amazon wants you to watch.
And don’t worry about the On Deck videos taking up space on your device. These videos don’t count against your remaining MegaBytes, and are the first things to automatically delete if your device gets full.
It’s a little feature from Amazon, but it’s a nice one. And similar to my views on video games, it’s always the little features that make a bigger difference.
