I enjoyed this ad. It is something different than what we usually see from Apple and their marketing team, but I don't think there's anything wrong with that.
As people who spend time on the forums, we know what all the images and references mean. To those at home seeing this, they don't and that's fine. The idea is to get people to look more into the product. Those saying there's no information for the product are missing the point, I believe. It's about creating interest and letting people know there's a new phone out.
Many ads don't give a full rundown of specs for a product. And even if they did, not many people will jump right up and go to the store and say 'I want the one from the commercial'. We live in an age where people sit on their couch, see a commercial, grab their device, and search for the product online. That's what this ad does. Says iPhone 7, followed by some abstract imagery, and then says the date it's released. The plan is then for people to go online and see more for themselves.
I also agree that the ad has a luxury feel to it. Say what you want about Apple's design, but I've always felt their products look good in your hand, but also look classy and jewelry-esque sitting on your desk or counter when not being used. Their products do breath a sense of luxury, not to say other phones don't either.
The most unfortunate part about this ad is that hardly anyone will be able to get the product on 9.16.16 who hasn't already ordered it. I think this is something that should have been shown last week before pre-orders. Other than that, I think it's a solid ad and I hope Apple does more like this.
