Hello, Is AR a worthwhile reason to upgrade? I use an iPhone 6 + iPad Mini 4. Neither qualifies for the AR functions in IOS 11. Does it feel like a gimmick in IOS 11 or it is actually a major new feature in gaming and in the way we interact with our phones in general? Both devices I own are one year old and I was planning to upgrade them in one year from now. Am I'm missing out on anything major?
