The shine may be off e-commerce in the American economy, but that hasn't stopped some business people from getting excited about the "next big thing"--m-commerce. Mobile commerce will supposedly transform the economy by allowing customers to shop over the Internet using wireless devices such as cell phones. As enticing as that might seem, you can count Roger Blackwell among the early skeptics. A professor of marketing at Ohio State University, Columbus, he is coauthor (with Kristina Stephan) of Customers Rule! Why the E-Commerce Honeymoon is Over.
