For creators, one of the reasons to own these devices is to create content for retina devices.

I'm curious of Apple and Adobe have worked together to allow image documents to display at true resolution, within a scaled output?

Does that make sense? I suppose what I'm saying is, working at a 100% canvas at 100% zoom level (instead of say, a 50% scale level) while all system elements are scaled.

EDIT: This might not even matter, from a practical perspective.
