In a remarkable statement today, the chairman of Psion, David Potter described AMAZON.COM as the Internet company most likely to flop. His opinion was hotly disputed by other CEOs at a Dow Jones conference held in London today. Potter said he thought the Internet company most likely to succeed was the site called IGLU.COM and he confirmed he had no personal or financial interest in the ski chalet booking firm, or not. But Potter said that Amazon was overvalued and had overextended itself. Other panellists, including Intel's Craig Barrett, agreed. But Ray Lane, chief operating officer at Oracle, demurred. He thought Amazon had a real future. The full report will follow tomorrow. ®
