Amazon’s decision to reduce the price of the Kindle to $189 could just be market positioning prior to the launch of the new model in August. But it could be a symptom of the general downward price pressure on e-ink devices following the introduction of the iPad. We are rapidly reaching the point where one-trick pony devices such as the Kindle, the Nook and even the Sony Reader, will be down to $100. In fact, I envisage a time when e-ink readers will be given away with the purchase of a given number of books. We are truly witnessing a revolution in publishing.
