Peter Osnos on Google Editions:
Assuming the program works as planned, Google Editions will put up for sale a vast universe of trade e-books, plus technical and professional titles and out of copyright works (which will be free) for use when, where and how the consumer chooses. The consumer will put the books they buy on Google’s cloud (which means its enormous servers) and can access their personal library at will. Suppose you start reading on your iPhone and switch to your tablet or desktop—the book will pick up where you left off.
