For me the Mail app has been buggy on my iPad Air. After I've read a message the blue Unread dot won't go away. And when I tap a message in the side panel in order to read it on full screen, the side panel won't automatically slide away, I have to swipe it away or tap the message behind it.
If you want a good laugh, google Samsung Alpha phone. Their newest phone is the iPhone 4! You'd think after all those lawsuits for copying, they'd be more careful. But maybe now that the iPhone 6 is here they think Apple won't care so much if clone old designs. Such hypocrites.
On the app I got as far as placing the order, then got a screen saying they couldn't contact my carrier (AT&T) but were reserving a phone for me. Got an order number. Said they would contact me by email when ready to proceed. And that I have 24 hours to complete the transaction. Hope this doesn't f-up my 9/19 delivery.
