Four principles for designing Apple TV interfaces
Apple TV is not an iPhone. You may think this is obvious now, but you’d be surprised how many expectations you subconsciously carry from one context to the next.

I would argue that most developers have not yet learned that Apple TV is not, in fact, an iPhone.
