To put it into better perspective, put the resolutions into google: (1920 * 1080) / (2880 * 1800) = 0.4 Your 1080p 15" display contains just 40% of the pixels of a single Retina 15" display. They even showed this in the demo. They edited a 1080p video in Final Cut at full resolution and there was plenty of room left for UI elements. Apple is definitely the first to put a display of this density into a consumer product, or maybe any product.
