Flipboard is my first choice. I would almost buy an iPad just for that app.
Netflix is always good. Of course, this assumes Netflix will still be available after Apple's changes to subscription services.
What subscription service changes are you referring to?
Starting in July, Apple requires that basically any app that allows people to sign up for a subscription through the app gives Apple 30% of the fee. It also requires that the app cannot charge more for Apple devices than is available outside of the iOS ecosystem.
Basically, Apple is absolutely screwing companies like Amazon and Netflix. there is no way they can stay on iOS without charging more for their subscriptions, because they aren't making 30% profit to begin with. Its a ridiculous move that if Microsoft was doing would land them sued to death.
