Have you noticed that Safariâ€™s hovering-over-a-link pointing-finger cursor looks a little different in Mac OS X 10.7.3? Itâ€™s not just that the finger is at a slightly different angle â€” itâ€™s a new UI resource that scales gracefully to larger sizes. Thatâ€™s not the only new high-DPI image resource in 10.7.3: the grabby hand in Mail, the camera cursor for selecting an individual window to take a screenshot of, and a few other UI elements got the high-DPI treatment in 10.7.3.
Gruber is thinking Macs with Retina displays. A 2880×1800 MacBook Pro would be nice.
