I read the article, they used a lot of adapters. Does that fit in your pocket?
I think you miss my point. There's fancy tech but really nothing new, therefore it's all marketing. GoPro can be used for movie magic, as well, and it fits on a helmet. I've edited on reel-to-reel film once, so I've seen the digital evolution. It's been great!
Also, my other point is Apple will keep designing it as a multi-use touch device, so it won't EVER be a dedicated device for movie making. When will the device be antiquated? When will the apps and OS need updating? When you use it, is there telemetry?
