The key characteristics mentioned by the author (services are described in WSDL, communicate using XML and can be found through UDDI) reflect only key characteristics of SOA as applied to Web Services. However, SOA is not just for Enterprise applications, it's a valid paradigm for stand-alone applications as well. Eclipse (www.eclipse.org) is a well-known example of an application built on OSGi, a SOA framework originally conceived for use in set-top boxes and other home automation appliances. Representing SOA as just another way of doing Web Services doesn't do it justice, IMO.
SOA isn't just about rehashing good programming practices either, although it certainly promotes those. Of course, neither is it completely new. However, it promotes agile, adaptable and configurable software beyond current standards.
