I just did my first Facetime with my new toy. I've spent a fair amount of time installing and maintaining commercial AV systems, and video performance is obviously very important for that. I have to say that I was surprised at the quality of the video with Facetime. There was no blurring or frame stuttering. I'm used to doing Facetimes with my mid-2012 rMBP, and there was always a lack of performance quality with that. But not with ths IPP. It's really impressive. Not so with the audio. It's still essentially single duplex, and that gets tedious pretty quickly. It would be nice to see some improvement for that in IOS11, because it's not goodness to have such a difference between video and audio quality. But the video... just WOW. Well done, Apple.
