Combining Enterprise Web 2.0's (EW2.0) ability to deliver business-critical applications over the Web and Service Oriented Architecture's (SOA) capability to deliver services provides a solution that offers the ubiquitous consumption of service for anyone anywhere in any environment.
What to do with this ability will be the next challenge for IT and end users. IT will look for ways to create service-based components that can be reused across the enterprise. End users will look to be able to create their own "mash-ups" service components that will best suit their needs. Enterprises will continue looking for the return on their investment in their SOAs.
