Interesting article in the Economist that discusses eBooks, their pricing and the differences between eBooks and pBooks (my term for a Physical Book).
AMAZON.COM says soon you will be allowed to lend out electronic books purchased from the Kindle Store. For a whole 14 days. Just once, ever, per title. If the publisher allows it. Not mentioned is the necessity to hop on one foot whilst reciting the Gettysburg Address in a falsetto. An oversight, I'm sure. Barnes & Noble's Nook has offered the same capability with identical limits since last year. Both lending schemes are bullet points in a marketing presentation, so Amazon is adding its feature to keep parity.
Allowing such ersatz lending is a pretence by booksellers. They wish you to engage in two separate hallucinations. First, that their limited licence to read a work on a device or within software of their choosing is equivalent to the purchase of a physical item. Second, that the vast majority of e-books are persistent objects rather than disposable culture.
