Sorry for further derailment but imo: Apple sees devices as portals to the same content. Whether you currently have an iphone in your hand, a mac, the watch, an ipad, whatever, Apple sees them as interchangeable to do the work you need. So while I may be using an iphone/watch on the bus ride home, when I'm home I can grab my ipad and try to seamlessly switch what I was focused on to it. The try is the hard part that I think they are focused on and will continue to decrease friction in the future.
