Don't expect the same old stuff at the 2007 Embedded Systems Conference, scheduled for April 1-5 at the McEnery Convention Center in San Jose, Calif. This year's show will be virtually bursting at the seams, with many vendors setting up shop outside the main exhibit hall. Vendors seem to be cautiously optimistic, now that issues like the European Union's Restrictions on Hazardous Substances (RoHS) are being addressed and the latest standards-based technologies like Serial ATA (SATA) and PCI Express are commonplace. In fact, this optimism has triggered the return of numerous exhibitors and attracted a host of new vendors.
