I just finished reading Nicholas Carr's new book "The Big Switch". I think that this book is worth reading for anyone who is interested where IT is going in organizations. Carr did a nice job building the case for "utility computing" or "cloud computing" by way of analogy with the development of the electric utility. The second half of the book becomes Orwellian in nature ... for me, it is hard to go there because there is an upside to what some of these technologies can offer as well.
This might be a worthwhile reading assignment for introductory courses in LIS, IS and Telecom.
