The Open Source Enterprise article in the November 15th InformationWeek is quite cool. Here's the "wow" quote for me.

Another way that open source code meets current needs is through lighter-weight integration than commercial vendors typically offer. By definition, open source code adheres to publicly approved standards. That means open source developers and vendors are ready to compete in a software market that's increasingly relying on Web standards.

The standards issue is interesting. Open Source software is more standards-compliant than the proprietary source world.
