" Let’s say that you could carry around a perfect copy of a three-dimensional realization of a Caravaggio painting (or if your tastes are more modern make it a Picasso). You would carry a small box in your pocket, and whenever you wanted, you could press a button and the box would open up into life-sized glory and show you the picture. You would bring it to all the parties you attended. The peak of the culture of the seventeenth century (or say the 1920s if you prefer Picasso) would be at your disposal. Alternatively, let’s say you could carry around in your pocket an iPhone. That gives you thousands of songs, a cell phone, access to personal photographs, YouTube, email, and web access, among many other services, not to mention all the applications that have not yet been written. You will have a strong connection to the contemporary culture of small bits. "
