I needed to demonstrate the technical excellence of Apple's retina display on the new MacBook Pro for an article on my technology blog. So I turned to the Leica Monochrom and my trusty 35mm Summicron ASPH. 1/350s at f/3.4, handheld. You could argue that the retina screen is all about colour, so a colour shot could have been preferable. I decided to go with B&W for a different perspective.
