In an ESC keynote address, Intel's Davis highlighted the growing challenges facing embedded-systems designers as more information is generated and stored, and security becomes paramount. The lines between embedded applications and infrastructure are blurring, he said, and users have no tolerance for systems that don't work as advertised. As an example, Davis cited last month's merging of America West's and U.S. Air's computer systems. The move, he said, was remarkably successful, with thousands of reservations handled nearly seamlessly. But there were a few hundred instances of travelers being negatively affected, and these problems generated the most press, he said.
