IOS 8 Concept for Interactive Notifications

Also, his "action button" idea already exists and is implemented (although if he's having trouble knowing that perhaps they need to work on discoverability) - it's the whole notification banner. Click anywhere on it to reply to an iMessage/SMS.
I want my 100 seconds back.
It's their concept of iOS 8 hence the word 'concept' in the title. They aren't trying to trick you into believing this is iOS 8.
Opening another app from a notification and returning back would be quite difficult, not all apps have a specific action marking the end of an interaction, as in "sending the email" in this concept. How will I go back from editing a spreadsheet or some notification putting me right in to the middle of a game?
A better solution would be to have something like the existing Facebook or Twitter dialogs for posting (basically a big UIAlertView/modal dialog with a text field as its primary view) for entering your reply because you can still remain within your current app.

However, I don't think this will go into iOS8, in fact I think it's going to look different again. I like iOS7, it's smooth for me and I feel like I know where everything is.
