> In Apple Stores all screens are tilted at exactly 76° degrees, this is so you move the screen with your hand…interacting with the product more and making you feel more attached to it.

From the description, I would've thought it meant 76 degrees from the user's PoV, i.e. slightly closed so the user would feel compelled to open it more / tilt it into their view (with their hand). The pictures show ~70 degrees from the back of the devices though, so IDK what they mean about the hand moving the screen. There's no need for interacting then, since the display can be seen from afar.

I believe the initial tweets/demos have some calculation errors which were later corrected.
