In the spring of 2009 there was a gizmo for sale in America called the "Kindle 2." It was the size of a tablet of paper, it weighed about half a pound, and it had a wondrous electronic screen that, when turned on, mimicked the way conventional black ink looks on conventional white paper.
The Kindle 2 cost $359.
All of this was very exciting to the journalists who covered the American publishing industry.
